Initialization of repository with code that parses Pinnacle files
into python dictionary objects

Files:
	pinn.py : 	Translate pinnacle file into JSON format text string.
		  	Parse JSON string into dicom dictionary and convert to
			pinnObjDict and pinnObjList objects.

	pinnObjDict.py : Subclass of python dict allowing navigation of
			a python dictionary object using a '.' syntax,
			which is more similar to Pinnacle Scripting language.
			Also allow tab completion in ipython and add a dir()
			function for easy exploration as in PyDicom

	pinnObjList.py : Subclass of python list allowing selection of objects
			with terms such as 'First', 'Last and 'Current'. Cast
			dictionary elements into pinnObjDicts before returning
			them.
