[newfield_revision] Patch: Support Multimaterials

[Jeffrey Oldham]

This patch finishes Stephen Smith's field revisions began today.
Fields have two dimensions: materials and centering values.  We add
better support for determining the number of materials and centering
values as well as initializing fields.  The underlying implementation
still makes differentiating a multimaterial field with one value per
material from a unimaterial field with a centering with multiple
values; this is on Scott's todo list.

Also, we add some error checking for centerings.

The newfield_revision branch is a development branch supporting
collaboration between filesystem-separated collaborators.  Compilation
and correctness on the branch are not guaranteed at any time.
