Add OutCall class to CustomTypes.
Remove score from parameters accepted in constructor for CustomTypes
Class and Method.  Score initialized to 0 and a setScore method is added
to Class and Method.
Add parameters in_DocLines and in_ComLines to constructor of Method and
XMLParser now searches for "docLines" and "comLines" attributes inside
Method tags.
Add method to check if an OutCall is from within a module or not.  Add
free method that takes in the list of packages and sets the boolean
value of withinModule for each OutCall.
Call setInModuleBools() in main method.
Fix some bugs with adding duplicate outCalls.  Now adding a duplicate
outcall will only result in the OutCall's field numCalls getting
incremented.
Change setInModuleBools to return a list of all outcalls.
