Added CoPylot - has CoPylot parent class and derived classes
Pylot_Component and Pylot_TestCase from which to further derive for
specialization at the component level.

Minor updates to config values/structure.

Added Settings\EC_Validations to house the Environment settings specific
to EC Val.

Added Settings\environment to house environment settings that are global
(e.g. HDFS info)

Added Test Cases\EC_Validations to begin building the Test Cases.
Currently working on the design architecture of the Test Case concept.
Want to get a fairly easy key : value interface that constructs the
eventual TestCase object, and to have it associated by a single name
(another key : value most likely). Also want to keep the concept of Test
Suites (set of Test Cases).
