Capability and command refactor:

 - Capability accepts the VNTRequest instead of the file url and the InPNetwork.

 - InPNetwork is built in capability, not in command.
First sample test. Refactor needed:

	- Create toString methods.
	- MappingResult extracted to a single .java.
All tests created + codestyle.
Added comments to requests and topologies files.
Declare classes in own .java file + refactor of methods from public to private.
Attirbutes with getters and setters. Old git references to classes removed.
Replace System.out for log.info
Capability output modified - TODO change tests.
MappingResult and MatchingResult included in capability output.
VnMappter includes mapping and matching state - commands ands tests changed.
