java port of perl's PPI modules
this project is built using a mixture of tycho and regular maven jar features. in order to import this project into eclipse, all of the project's dependencies must be available as plugins in eclipse - how you choose to achieve this is up to you.
once installed, the project can be imported as an existing maven project, however, a side effect of using this mixed maven structure means the test sources need to be manually added to the build path.
