[Feature] Use namespaces

[GoogleCodeExporter]

What do you guys say that we take this lib to the modern PHP? Maybe bump it up 
to 0.7.0? I have some changes in mind:

* Use namespaces and remove all "require" statements
* Use composer
* Remove the code that automatically executes

It is not a big change. I ported this lib a couple of months ago. I remember 
that it took med 2 hours or so.. But I did not port the test code...

Is anyone interested in such changes?
