Description:

a pluggable node visitor.
setup with:
    actionForNodeClass:aClass put:aBlock
    
for example, if you are only interested in assignments,
use the following code:
    |v|
    v := PluggableParseNodeVisitor new.
    v actionForNodeClass:AssignmentNode put:[:node | Transcript showCR:node. true].
    v visit:(Parser parse:code in:someClass.

Instance protocol:

 actionForNodeClass: aNodeClass put: aBlock

setup so that for nodes of type aNodeClass, aBlock is invoked.
If the block returns true, subnodes (eg. right side of assignments, etc.)
will be enumerated as well.
Otherwise, no subnodes are visited.

 passByNode: aNodeObject

redefined to look for an action for this node's class.
If there is one, it can specify if subnodes are to be visited too

 visit: aNodeObject

redefined to look for an action for this node's class.
If there is one, it can specify if subnodes are to be visited too
