PR #46: Subgrid size change and FOF bugfix

[John Wise]

Hi everyone,

Here's a pull request that I just submitted that contains some minor
changes, but it will affect all simulations because it adjusts the
limits of the maximum subgrid size.

Title: Subgrid size change and FOF bugfix

There are two changes in this PR.

1. I've adjusted the MINIMUM_SIZE and MINIMUM_EDGE to 2000 and 4, so
grids aren't too small when determining the maximum subgrid size. Also
this avoid many small grids when a level is suddenly flagged for
refinement, like during initialization or must-refine regions.

2. Thanks to Manodeep Sinha to finding a couple of bugs in the FOF halo
finder. This affected the r200 calculation in halos that straddled
periodic boundaries.
