Reformat

Refactor without changing any logic, just structure.

Few things: 
1.) Delete unused test cases
2.) Reduced Namespace for easier typing
3.) psr-4 type folder structure with simplified one.
4.) psr-1 & pasr-2 coding standard :package: 

and sorry got rid of you name in Namespace. The library is already packaged under your Namespace, so, I don't deem its necessary to have it in the file, as it'd save someone some typing space :)
