DOC: Fixes LaTeX build error
The PDF doc build was chocking on the `Parameters` section being the first item.

I might be pushing a few more stylistic changes here, so maybe hold on merging. e.g.

 @TomAugspurger at your leisure
 One API question, do we want to expose `Resampler` at the top level, similar to `Grouper`? The methods like `Resampler.fillna` weren't being linked to correctly in `api.rst`. Rebuilding now, but it may have been because `panads.Resampler.fillna` isn't a thing. Would need `pandas.tseries.resample.Resampler.fililna`.
 Actually, that seems to be an issue just with my build, as the traivs docs have it linked correctly: http://pandas-docs.github.io/pandas-docs-travis/api.html#resampling
 hmm, btw make sure that in your doc-build env you actually have an _installed_ pandas of master/latest (you can simply install from conda), as it doesn't use the current one (as you are in `pandas/doc`)
 side note, this is master: https://travis-ci.org/pydata/pandas/jobs/115054959

there is a seg fault right at the end of building the docs (before all of the `create *` stuff). Any idea what that is from?

I don't get this locally.
 @TomAugspurger ok I am pretty much done with doc changes. So pls build at your leisure (or you can wait for the final tag prob sunday eve)
 Ok, I'll merge this, and then build later tonight probably. You're last suggestion about having a real install fixed the link issues.

Not sure about the segfault in travis. The error this is fixing does occur towards the end of the build, but is probably unrelated. I'll look into it tonight.
 gr8

yeah I noticed the segfault as was looking thru logs

i bet it's for the latex building on Travis 
 actually. let's let everything turn green. I'll push the 0.18.0 tag later today. You can build (and if anything else you need to fix, just include it and do a PR later). Then can release on sunday.
 just did a quick build. Seems like the API reference is having trouble with the accessors (.str, .dt, .plot). It's also not linking /building those properly in the dev build. http://pandas-docs.github.io/pandas-docs-travis/api.html#string-handling Other than that, things seem ok at a glance.

Gotta run for now, but I'll investigate later.
 thanks @TomAugspurger lmk.
 @TomAugspurger about the API docs, yes, that is a known issue: https://github.com/pydata/pandas/issues/12161. I intended to look at it, but won't be able to do this for 0.18.0. I can do it later in April, but if you can have a look now, great! (but if you cannot directly fix it, it shouldn't hold up the release. Another possibility is building with 1.1.3, which I thought still worked but I am not sure).
 Oh, I assumed that section in the wiki with sphinx==1.1.3 was just out of date :)

I’ll try both 1.1.3 and seeing what’s wrong.

 Well, it should be :-) 
It's possible that it works with 1.2 as well, but I switched to 1.3 for speed (otherwise it wouldn't finish in time on travis). The reason we were still using 1.1.3 is that the API docs were broken on 1.3 for the first minor releases, and only recently was fixed (and I wanted to wait for that to switch in one time from 1.1.3 to 1.3).

We should maybe actually also test sphinx 1.4, which is in beta.
 The instructions in the docs also need an update: http://pandas-docs.github.io/pandas-docs-travis/contributing.html#requirements (> 1.3.2 also works now: https://github.com/pydata/pandas/issues/10316)
