DESCRIPTION updated
Added files that were lost after merge d10cc51
Merged new form argument
testing local changes

This was just to see if I could commit changes.
Add formula-based models.

This does not include updates to the .Rd pages because it appears they
are auto-generated from header information in these files.  I have
updated the in-header documentation.
Undo previous test file.
This reverses d2528c6d0fd23061108979ce13598acddf213157.
A real ReadMe would still be nice.
Merge branch 'master' into multilevel
All conflicts resolve in favor of master.
