* add past paths for empty arguments etc * cache attribute token transform pipelines * fix bugs in TokenCollector and NoIncludeOnly handler, and improve its efficiency by only registering for 'end' tokens on demand * Remove empty reset methods from a few handlers * Add a simple 'ap' debug print function that makes it easy to only print some debug prints by temporarily changing 'dp' to 'ap' * Improvements and bug fixes in AttributeExpander Change-Id: Ie69729c8f62d48bba922712e44ebce484c621c50
