Parameter Case

So ive this a bit mixed up, in the api doc it does mention preference/need for all lower case, and this lib follows that, but i can from php api and camel case works. Without realizing i started using this library with camel case and it works, for searches... with the api even returning your results in camelcase , go figure...

But when i started to try doing transforms i ran into trouble, and had to switch to all lower case.

Thinking prob best to go back to all lower case...
