Recommendations regarding use of backticks in documentation

[mdhaber]

I believe that given token of code should by stylized consistently throughout documentation to help the reader recognize the token amidst plain text. In many projects, this is not the case; for instance, in the documentation of scipy.stats.bootstrap, data appears as:

bold, monospaced, italicized with background

italicized

bold

pink, monospaced with gray background

Before noon on 6/3, I'd like to focus on resolving one source of these inconsistencies: numpy/numpydoc#525.
