Description

A use case that arises when migrating a large project to v3: 

1) you migrate all the JCas classes

2) you run for a while to gain confidence in a mode where you can switch between v2 and v3.

During this time, some incremental changes happen to the v2 JCas classes, and you want to migrate just the changed class.

Extend the meaning of the -sourcesRoots argument to allow it to point to a single JCas source file, and have the migration tool migrate just that one.
