This completes the removal of Painless Type. The new data structures in the definition are a map of names (String) to Java Classes and a map of Java Classes to Painless Structs. The names to Java Classes map can contain a 2 to 1 ratio of names to classes depending on whether or not a short (imported) name is used. The Java Classes to Painless Structs is 1 to 1 always where the Java Class name must match the Painless Struct name. This should lead a significantly simpler type system in Painless moving forward since the Painless Type only held redundant information since Painless does not support generics.

The license header seems to be messed up in this file. It should be before the package statement.

Huh, this file hasn't been modified much so it's probably legacy. Will fix.
