# Name:          athenaObj.py
# Purpose:       defines the following objects:
#                    External: find all necessary files, prefs, xml data
#                    AthenaObject: data container for athena object
#                    Terminal: object interface for terminal display
#                    Interpreter: object for parsing commands, logging, help
