Path beta 0.1b

In this version, the interface of the Path library has gone through some radical changes and should be much easier to use and adapt to special needs.

The demo project now also includes a unit controller for units using the unity character controller interface which also demos how animation could be used in Path projects.

Also a range of bugs have been corrected (and no doubt new ones introduces so please toss all the feedback you can come by at me). Last but not the least Path is now almost feature complete which means feature requests will be considered at this point.

Dig in!
