The `<value>` tag remains for scalar parameters.\r\n   This is needed for the [Mechancis PR](https://github.com/ufz/ogs/pull/1340) where the initial conditions are multi-component, constants. Before we had multi-component InitialCondition, which is replaced by Parameter.\r\n - Also add two Parameter::operator() for scalar and component-wise value access. This is for convenience: `rho(t, x)` for scalar parameter rho, or `K(t,x,i)` for three-dim conductivity/permeability parameter K (accessing the i-th component) is much nicer/less noisier than `rho.getTuple(t,x)[0]` or `K.getTuple(t,x)[i]`."},"comment":{"url":"https://api.github.com/repos/ufz/ogs/issues/comments/243045531","html_url":"https://github.com/ufz/ogs/pull/1378#issuecomment-243045531","issue_url":"https://api.github.com/repos/ufz/ogs/issues/1378","id":243045531,"user":{"login":"TomFischer","id":800065,"avatar_url":"https://avatars.githubusercontent.com/u/800065?v=3","gravatar_id":"","url":"https://api.github.com/users/TomFischer","html_url":"https://github.com/TomFischer","followers_url":"https://api.github.com/users/TomFischer/followers","following_url":"https://api.github.com/users/TomFischer/following{/other_user}","gists_url":"https://api.github.com/users/TomFischer/gists{/gist_id}","starred_url":"https://api.github.com/users/TomFischer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/TomFischer/subscriptions","organizations_url":"https://api.github.com/users/TomFischer/orgs","repos_url":"https://api.github.com/users/TomFischer/repos","events_url":"https://api.github.com/users/TomFischer/events{/privacy}","received_events_url":"https://api.github.com/users/TomFischer/received_events","type":"User","site_admin":false},"created_at":"2016-08-29T06:52:09Z","updated_at":"2016-08-29T06:52:09Z","body":":+1:"}}
