DOC: tslib.monthrange

[cancan101]

Does Pandas have its own tslib.monthrange rather than using calendar.monthrange for performance reasons?

If so, I will toss some comments on it indicating such.

[jreback]

@cancan101 yes; these are basically direct c-calls

if you REALLY want a project, would like to write c-based date-parsing code that replaces dateutil, which is buggy
and slow

(big job though)

[cancan101]

@jreback I am not volunteering that; I am just volunteering to add some comments to tslib.monthrange to explain what that method (and perhaps some other methods from tslib) does and why it exists.

[jreback]

ha!

sure...docstrings for these would be great

[jreback]

pushing to 0.14, but @cancan101 welcome a doc PR anytime

[jreback]

@cancan101 doc PR for this?
