Getting odd error on Windows

Solved!
Seems the module makes Unix style file locking calls using fcntl.

@Callero ACK. congrats, you're our first confirmed Win* user!

Thanks for pointing this out to me. Though the problem in that SO thread was for file-locking, that's not exactly the case in this module. Specifically, in these highlighted lines here:

https://github.com/tbielawa/bitmath/blob/master/bitmath/__init__.py#L65-L68

The fcntl library is actually used much later in the module for calculating system disk capacities (reference: https://bitmath.readthedocs.org/en/latest/module.html#bitmath-query-device-capacity )

I think what I can do for you for now is add a conditional around those imports so they only evaluate on supported *NIX systems.

Following that quick-patch I'll open a new issue on the tracker to see if I can implement Win* support for device capacity reading. I think AWS has cheap enough Windows instances to test on.

Throwing a patch together right now that will fix your import error. Do note however that the query_device_capacity function will be unavailable until I can implement support for the proper system calls on windows.

@Callero if you would like to be notified of when windows support is available for the query_device_capacity function, please add yourself to the referenced issue: #52

Wow, lightning reactions there =)
Thanks!
