allow language to be specified when executing a script

[corbinbs]

Hello,

We recently released https://github.com/pokitdok/gremlin-python and we'd like to use rexpro to easily submit python scripts to rexster for execution. (https://github.com/pokitdok/gremlin-python#rexster) It looks like everything is in place to do this now and we just needed to allow the language parameter to be passed in when running execute

I ran the tests locally and all of the current tests still passed:

corbinbs@~/Projects/github/rexpro-python (venv) [master] $ nosetests
............................................................
----------------------------------------------------------------------
Ran 60 tests in 6.863s

OK

please consider adding this so folks that drop gremlin-python into their rexster server can easily execute python scripts with rexpro.

Thanks for the great rexpro python library!

Brian

This is Great! I was just reading about pokitdok/gremlin-python on the mailing list! Think you could add some example documentation on using it as a general approach? gremlin-python could be the prime example.

[corbinbs]

happy to add some documentation!

where's the best spot for me to include it along with this pull request? In the readme or somewhere in the docs folder?

Somewhere in the docs folder, maybe create a new "examples" directory like I've done with mogwai?

[corbinbs]

Sounds good - I'll give that a shot later this afternoon and post for your review

[corbinbs]

I took a shot at dropping in some examples to illustrate some of the basics There are a lot of other scenarios that could be included in the examples that are part of the gremlin-python test cases, but I've not had a chance to add all of them in here yet.

Is this close to what you were thinking for building out an examples directory?

Looks great! Thanks! I'll cut a release soon and post to PyPI

thank you!
