Refactoring to move to one plugin and removed unused classes. (#138)

* merge

* changed varrs

* reset test

* First iteration

* it compiles, although renaming this is still neccessary

* added source

* cleaned up, tests still need to pass

* post merge clean up

* validation updated, validation tests are now passing

* Addressed comments from Jesse

* last Jesse comment, convertISDToModelState doesn't check if pointer is invalid anymore as the sensor model should except

* model_name -> m_modelName for frame getState

* copy paste error in FrameSensorModel
