2) Add correct dependency in pom.xml

about function calls.

a rule for running it in the Rakefile.

Add:
    parser_server.rb:
        - listens for connections from the python client process

    parser.rb:
        - creates a syntax tree from the input and returns relevant data
          about it to the client

Mod:
    Parser.java:
        - Moved client reading and writing methods to the abstract
          parser class, so that it is not specific to the JavaParser

    JavaParser.java:
        - Implemented NodeVisitor._cache.  The cache is a stack of data
          packets.  When a node that we want information on is first
          visited, a new packet of data is pushed onto the stack.  The
          child nodes of that original node than add information to the
          packet, and when the original node is traversed again on the
          way up the tree, the data is popped from the cache and added
          to the symbols.  This makes it possible to gather information
          about various levels of the tree easily.

    JavaSymbols.java:
        - Refactor all the insertMethods to simply add a packet of data
          to the appropriate HashMap.

    Symbols.java
        - Add a createCoord method which returns an arraylist
          representing a point in a document.

Parse.java:
        Added comments

    JavaParser.java:
        Updated the genSymbols method and a private class 'NodeVisitor' which
        implements ASTVisitor.  genSymbols returns an instance of the
        Symbols class containing all relevant data about the Java code.

    JavaSymbols.java:
        Add fields which map class, interface, method, field, and
        variable names to positions.

Add:
    c.py
        - CTreeCutter class is very similar to PyTreeCutter. It utilizes
          self.cache as opposed to PyTreeCutter which doesn't yet.
        - CTreeCutter visit functions simply add start and end lines of
          the node to the cache, and visit_Decl pushes the cache onto
          accum.
        - parse_c performs a task identical to parse_py.  However, many
          c files need to be pre-processed before they are parsed.

Mod:
    python.py
        - Add self.cache to allow for saving of unassocaited metadata as the
          PyTreeCutter moves down the syntax tree.
        - Update docstrings.
