Code style clean-up and documentation

The following changes were made:
- Clean-up of variable namings
- Addition of README
- Removal of num_cu and occupancy args; such options are meant for
  testing purposes and should not be exposed to the user
- Removal of CK_TILE_PIPELINE_MEMORY macro and PipelineTypeTraits class
  since we only support one pipeline at the moment.
