[code-reflection] Integrated: Mavenize the repo. Mostly file moves to maven layout form

[Gary Frost]

Maven wants an extra dir called 'main' in it's defaul layout. 

So this is mainly a bunch of moved files. 'src/java/pkg/MyClass.java' to 'src/main/java/pkg/MyClass.java' 

This simplifies pom.xml creation, we don;t have to force a non standard layout. 

I fixed up the CMakeLists.txt so the top level cmake will build

I fixed up the top level pom.xml (still non standard) and added pom.xml for all examples (using new standard layout).

I fixed up the Intellij *.iml files to reflect the new source and resource locations.
