Missing Graphics & Splitting Project

[SebastienGllmt]

If you look at the res folder, it contains 2 files which don't belong and should probably be removed. They should instead probably be replaced with the graphics that are referred to throughout the code (such as levels, grass, etc).

Also I think it may be useful to split this project into 2 parts. The problem we're having is that you're testing the engine in the same project you're developing it. We should maybe consider having 2 separate projects (one is the engine, the other is the implementation). Either that, or have a folder called /examples/ or something of the sort and put the implementation of the engine in there to make a clear distinction.

Perhaps we should use the fallowing source structure:

/src/main/java
/src/main/resources

for the actual engine, and:

/src/test/java
/src/test/resources

for the test code...

Thats how I do things. Works well..
