ASTWalker

ASTWalker - Provides a simple AST traversal utility that traverses all nodes / children regardless of type.

A callback object is provided in traverse which may contain two methods enterNode and exitNode which are invoked with the current node and the parent node respectively when entering and exiting a given node.

enterNode may return a array of strings which provide a set of children keys to ignore.

enterNode may also return null to skip traversing children keys entirely.
