Proper autoloading for composer, PSR-4 compliant, Cleanup

[gholol]

Hi, I was little pissed off with using include directive each time I wanted to use this library, so I rewrote it.

• PSR-4 Compliant (I know there's Lot of improvements in Geometries, Adapters and overall performance #125 but - it doesn't have fully qualified class names)
• Autoloading
• Minor coder cleanup

It works the same way as before, but instead of include you have to use the use directive.

Tests are gonna fail (obviously). I don't found the time to rewrite them.

careful... the shorthand notation for array was only introduced in 5.4. The composer minimum php versions should be updated or keep it as array()

Are these changes automatically generated by your ide? Or are you doing them manually?

If manually - can we replace w/ ===?

@gholol Chris, great work! This is a huge milestone for this project.

@phayes - Patrick can we please put this on the roadmap? I am happy to personally oversee the transition and rewriting the tests at some point.

I am thinking we should:

1. Create a new tag and lock the current codebase at the current version (pre namespacing)
2. Merge pull request
3. Increment the major version and create a new tag w/ the namespaces.
4. Update the README.md file w/ instructions how to install pre-namespaced code vs. new namespaced version.

While this approach isn't perfect -it does offers pretty good backwards compatibility.

Tests are very much important. But given how important namespacing is for a proper PHP project - I would be okay w/ making a one-off exception. I am currently using a namespaced version of this repo in production and all works 👍 .

Suggested change

	using Phayser\GeoPHP\GeoPHP;
	using Phayes\GeoPHP\GeoPHP;

there's a typo there

@phayes - Patrick, this makes a whole lot of sense to do at some point (even 5 years later lol)
