Handles generation of code for the @WithReadLock and @WithWriteLock annotation.
This transformation adds an instance of ReentrantReadWriteLock to the class.
Any method annotated with @WithReadLock will obtain a read lock and release it in a finally block.
Any method annotated with @WithWriteLock will obtain a write lock and release it in a finally block.

The method is invoked when an AST Transformation is active. For local transformations, it is invoked once
each time the local annotation is encountered. For global transformations, it is invoked once for every source
unit, which is typically a source file.
nodes - The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this
annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For
global transformations it is usually safe to ignore this parameter.
source - The source unit being compiled. The source unit may contain several classes. For global transformations,
information about the AST can be retrieved from this object.
