All Classes Included

All of the classes are now included. The Load Balancer Class has two missing functions, create and update, but those will be forthcoming. There is also one function in Reserved IPs that is outstanding - waiting on clarification from Vultr. Once I have the final doc from them, I'll implement that change.

I also plan to create docs for each individual class and add more error checking and tidy up the code in general but I wanted to get a complete wrapper out for all of the v2 endpoints. Didn't have to be pretty, but had to be complete.
