Glossaries native support with examples in default template

[mpacer]

It should not be hard to use the glossaries LaTeX package as part of the default template.

If I have time, I may try to implement a version of this for the Berkeley example.

One nice feature is that because glossary terms are only included if they are actually used, if people were to begin writing a uber-glossary from the beginning of their graduate studies, they could use that same glossary file in their dissertation.
