Description

We should split the existing JCAS class into an interface org.apache.uima.jcas.JCas and its implementation org.apache.uima.jcas.impl.JCasImpl. This follows good design practices and also is consistent with the rest of uimaj-core. It is important to do this prior to our first release since it will be a non-compatible change for user code.
