[yt-dev] species naming

[Matthew Turk]

Hi all,

Just wanted to make sure everyone had an opportunity to comment on and
look at these pull requests:

https://bitbucket.org/yt_analysis/yt/pull-request/719/adding-some-species-handler-helpers
https://bitbucket.org/yt_analysis/ytep/pull-request/34/proposed-names-for-species-fields

They propose new naming schemes for species fields, and then implement
them for Enzo.  You can see the translation table in the
enzo/fields.py file.
