/**
* This is the Entry-Point of program and responsible to:
* - read the command-line parameters to create a CommandParameters
* - next is to read the API-Contract by creating an APIImportConfig instance and calling getImportAPIDefinition()
* - the APIManagerAdapter method: getAPIManagerAPI() is used to create the API-Manager API state
* - An APIChangeState is created based on ImportAPI and API-Manager API
* - Finally the APIManagerAdapter:applyChanges() is called to replicate the state into the APIManager.
