This will be useful/necessary for depletion as well as calculating microscopic cross sections using our `openmc.mgxs` module. At the moment, if you request microscopic cross sections from `openmc.mgxs` over a heterogeneous domain, the cross sections are wrong because the code has no way of knowing what the average number density of nuclides are over the domain. This PR fixes that with the new capability.\r\n\r\n## Fortran implementation\r\n\r\nThere are new volume_header and volume_calc modules, the former which defines a `VolumeCalculation` derived type and the latter which contains the logic for running a calculation. Unfortunately I couldn't have everything in volume_header because of global variable use (that would result in cyclic module dependencies). A calculation can be run by specifying a `<volume_calc>` element in the XML file that looks like:\r\n```XML\r\n<volume_calc>\r\n  <cells>10 20</cells>\r\n  <lower_left>-10 -10 -5</lower_left>\r\n  <upper_right>10 10 5</upper_right>\r\n  <samples>1000000</samples>\r\n</volume_calc>\r\n```\r\nYou can have as many of these guys in settings.xml as you want. I think the input is pretty self-explanatory but in case it's not obvious: **cells** identifies cell IDs, **lower_left** and **upper_right** define a bounding box over which locations are randomly sampled from, and **samples** says how many times to pick locations. Volume is determined simply by counting the number of \"hits\" within a particular cell, dividing by the number of samples, and multiply by the volume of the sample region. At the end of the calculation a volume_*.h5 file is written out that contains, for each cell, the volume and total number of atoms of each nuclide (along with an uncertainty). The reason that I picked total number of atoms rather than number density is that we truly have the uncertainty on the number of atoms -- if we divide by the volume (itself a stochastic quantity) we'd have to assume that the volume and total number of atoms are completely uncorrelated (which they are not).\r\n\r\nThe calculation is fully parallelized and reproducible with both MPI and OpenMP. You'll see from the get_volume subroutine that it was a bit painful to reduce vectors, but this was done in the interest of not blowing up memory for a model with tons of materials. It's necessary to track hits in each unique material within a cell in order to properly compute an uncertainty.\r\n\r\n## Python implementation\r\n\r\nYou'll find a new `openmc.VolumeCalculation` object which both facilitates input generation and reading of results. Input generation is simple -- instantiate this guy and assign him to `Settings.volume_calculations`. You can see the property name implies a list, and indeed you can give it a list of these objects. On the backend, a classmethod `VolumeCalculation.from_hdf5` parses the HDF5 file and allows a user to get results. The very nifty `VolumeCalculation.atoms_dataframe` gives back a nice Pandas dataframe with the number of atoms of each nuclide in each cell, e.g.\r\n```\r\n   Cell   Nuclide         Atoms   Uncertainty\r\n0     1  U235.71c  3.481769e+23  7.979991e+20\r\n1     1  Mo99.71c  3.481769e+22  7.979991e+19\r\n2     2    H1.71c  1.399770e+23  2.072914e+21\r\n3     2   O16.71c  6.998852e+22  1.036457e+21\r\n4     2   B10.71c  6.998852e+18  1.036457e+17\r\n5     3    H1.71c  1.369920e+23  2.051689e+21\r\n6     3   O16.71c  6.849599e+22  1.025844e+21\r\n7     3   B10.71c  6.849599e+18  1.025844e+17\r\n```\r\nOnce you have volume calculation results, you can assign them to cells using `Cell.add_volume_information`, `Geometry.add_volume_information`, `Summary.add_volume_information` or `StatePoint.add_volume_information`. Statepoints now also auto-link stochastic volume estimates so if it sees volume_*.h5 files, it will attempt to load them and assign data to cells. This makes it very easy for a user to get microscopic cross sections over a heterogeneous region because all they need to do is specify that a volume calculation take place and all the data comes in automatically when `mgxs.load_from_statepoint` is called.\r\n\r\nOne cool feature on the Python side -- if the cells are defined such that the API can figure out a bounding box for all of them, the user doesn't need to specify the lower_left and upper_right arguments. This works for a lot of common cases. In fact, the new test for volume calculations takes advantage of this.\r\n\r\n## Limitations\r\n\r\n- Currently limited to cells (can't do universes or materials). I welcome any thoughts on how best to extend this capability.\r\n- Microscopic cross sections produced by `openmc.mgxs` don't account for uncertainties on average nuclide densities and volumes.\r\n- No option for user to explicitly give volumes / average nuclide densities. Might be useful in the event that the user knows these explicitly and wants to use them for depletion / micro xs calculations.\r\n\r\n## Other notes\r\n\r\n- `Settings.source` and `Settings.resonance_scattering` are now CheckedLists\r\n- I've renamed several methods `to_xml()` --> `to_xml_element()` which I think is clearer.\r\n- In the Python API, `get_all_nuclides()` was broken into `get_nuclides()` and `get_nuclide_densities()`, the former gives a list of nuclides, the latter nuclides along with their densities. Some `get_nuclide_densities()` methods have been removed (universe, lattice).","created_at":"2016-08-01T18:09:19Z","updated_at":"2016-08-11T16:38:53Z","closed_at":null,"merged_at":null,"merge_commit_sha":"4fb1881e19fa151e98d99575e72c90fa2f139b78","assignee":null,"assignees":[],"milestone":{"url":"https://api.github.com/repos/mit-crpg/openmc/milestones/15","html_url":"https://github.com/mit-crpg/openmc/milestones/v0.9","labels_url":"https://api.github.com/repos/mit-crpg/openmc/milestones/15/labels","id":1820404,"number":15,"title":"v0.9","description":"","creator":{"login":"paulromano","id":743095,"avatar_url":"https://avatars.githubusercontent.com/u/743095?v=3","gravatar_id":"","url":"https://api.github.com/users/paulromano","html_url":"https://github.com/paulromano","followers_url":"https://api.github.com/users/paulromano/followers","following_url":"https://api.github.com/users/paulromano/following{/other_user}","gists_url":"https://api.github.com/users/paulromano/gists{/gist_id}","starred_url":"https://api.github.com/users/paulromano/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/paulromano/subscriptions","organizations_url":"https://api.github.com/users/paulromano/orgs","repos_url":"https://api.github.com/users/paulromano/repos","events_url":"https://api.github.com/users/paulromano/events{/privacy}","received_events_url":"https://api.github.com/users/paulromano/received_events","type":"User","site_admin":false},"open_issues":8,"closed_issues":10,"state":"open","created_at":"2016-06-10T15:40:11Z","updated_at":"2016-08-09T02:55:30Z","due_on":"2016-10-31T05:00:00Z","closed_at":null},"commits_url":"https://api.github.com/repos/mit-crpg/openmc/pulls/688/commits","review_comments_url":"https://api.github.com/repos/mit-crpg/openmc/pulls/688/comments","review_comment_url":"https://api.github.com/repos/mit-crpg/openmc/pulls/comments{/number}","comments_url":"https://api.github.com/repos/mit-crpg/openmc/issues/688/comments","statuses_url":"https://api.github.com/repos/mit-crpg/openmc/statuses/0bfa509b3c330e46bf07d12f3cc629d1c66eaaa5","head":{"label":"paulromano:stochastic-volume","ref":"stochastic-volume","sha":"0bfa509b3c330e46bf07d12f3cc629d1c66eaaa5","user":{"login":"paulromano","id":743095,"avatar_url":"https://avatars.githubusercontent.com/u/743095?v=3","gravatar_id":"","url":"https://api.github.com/users/paulromano","html_url":"https://github.com/paulromano","followers_url":"https://api.github.com/users/paulromano/followers","following_url":"https://api.github.com/users/paulromano/following{/other_user}","gists_url":"https://api.github.com/users/paulromano/gists{/gist_id}","starred_url":"https://api.github.com/users/paulromano/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/paulromano/subscriptions","organizations_url":"https://api.github.com/users/paulromano/orgs","repos_url":"https://api.github.com/users/paulromano/repos","events_url":"https://api.github.com/users/paulromano/events{/privacy}","received_events_url":"https://api.github.com/users/paulromano/received_events","type":"User","site_admin":false},"repo":{"id":6039026,"name":"openmc","full_name":"paulromano/openmc","owner":{"login":"paulromano","id":743095,"avatar_url":"https://avatars.githubusercontent.com/u/743095?v=3","gravatar_id":"","url":"https://api.github.com/users/paulromano","html_url":"https://github.com/paulromano","followers_url":"https://api.github.com/users/paulromano/followers","following_url":"https://api.github.com/users/paulromano/following{/other_user}","gists_url":"https://api.github.com/users/paulromano/gists{/gist_id}","starred_url":"https://api.github.com/users/paulromano/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/paulromano/subscriptions","organizations_url":"https://api.github.com/users/paulromano/orgs","repos_url":"https://api.github.com/users/paulromano/repos","events_url":"https://api.github.com/users/paulromano/events{/privacy}","received_events_url":"https://api.github.com/users/paulromano/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/paulromano/openmc","description":"OpenMC
