Create basic structure of pap component
1) Creating the basic code structure of pap component which includes
main sub-module having Main, PapActivator, PapCommandLineArguments,
PapParameterGroup & PapParameterHandler. Along with few exception
classes. Basicalliy the structure follows the pattern developed in
policy/distribution component.
2) Created the related unit test cases and required test resources.
