Comparing MODS to MODS32

As part of changeset http://svn.open-ils.org/trac/ILS/changeset/10587 10587, dbs bumped the version of MODS in use from MODS to MODS32. This page will cover the investigation of the differences in those two schemas as it pertains to Evergreen's indices.

Global note: chopPunctuation and chopString is applied uniformly to text values in MODS32. This may be enough justification for a rebuild of all indexes as users migrate from 1.2 to 1.4. Some testing needs to be done to compare just how much of an effect this will have in practice.
