Changed the types and implementation of the buildFlowGraph function to add the new ASTModifier functions.
...
This patch is very large, because it contains all the required changes. Buried in there is a change in how Options are processed in Case statements; they are no longer shoe-horned into ExpressionLists, but rather create a Node for each Expression and chain them together.
