New issue 711: Expand upon unit handling. https://bitbucket.org/yt_analysis/yt/issue/711/expand-upon-unit-handling
Right now the unit handling docs are pretty bare-bones. The discussion should mention `_convert_function`, the LaTeX-formatted `unit` string, the idea of code units - pointing out that some fields are in code units, the idea of 'standard' fields with Enzo field names that are always in CGS, and native code fields that are (generally...) in code units.
Here be dragons.
