Format library

Will resolve #9

I have not yet changed any names, just ran the files through a formatter. @gigapod, you mentioned wanting to change some names away from snake case. I'm also not sold on all the names I chose. Do you have any suggestions?

[sfe-SparkFro]

Also, are the file names and directory structure okay? If we're going to change those, would probably be best to do that as part of this PR. And any other house-cleaning things like that, really.

Overall looks good. The only thing to tweak is the class names - see comment I left.

u-blox is preferred.
ublox 2nd choice.
(They prefer without capitalisation....)

@gigapod @PaulZC Changes pushed. Also decided to address #12 in this PR, and I removed a bunch of calls to ubx_cell_calloc_char() in favor of putting arrays on the stack; should help with preventing the heap from getting fragmented, and give a minor performance improvement.

Please take a look and let me know what you think! If all is okay, I'd like to get the first release out this week if possible. There's still a couple open issues, but it should at least be totally useable.

@PaulZC @gigapod Last call for input before I merge this early next week. Thanks!

Looks good - just one very minor comment/nit.
