ENH: add re.fullmatch

[rchurt]

Is your feature request related to a problem?

I want to find only strings that match my full regex expression, not just the first part of it.

For example, if I am searching for the string 'panda', and my series contains the strings 'panda' and 'pandas', I only want it to return 'panda'. Currently, using str.match('panda') returns both.

Describe the solution you'd like

Add support for re.fullmatch (https://docs.python.org/3.4/library/re.html#re.fullmatch) so that it can be called with str.fullmatch.

Can you use str.match along with ^ and $ anchors to achieve the same result? (Also simple equality works here, but of course only because we have a trivial regex.)

[rchurt]

Yup, that's what I ended up doing in my code, but I thought I'd post this here as a possibility to help those not so familiar with regex. I'll defer to you as to whether you think it's worth implementing or not.
