Successfull code gen for lenet

- String constant for node name passed correctly to wrapper API calls
- Some argument mismatches fixed
- Identified softmax missing - to be added
- Added string pass arguments and calls to init - clear RT controller.

- Added string for node name to wrapper API runtime calls
- No check for hint in leaf nodes, as all will be mapped to wrapper API
- To be tested when consistent with wrapper API

- Changes to agree to the new interface of tensor rt
- Changes to read from quantization levels file - for now only first line is
  read correctly

- InitRuntimeAPI changed to fully use tensorRT
- State machine changed to recognize single convolution
- Twine big fixed
- Successfull until codegen - failing due to new API needed for
  quantization ranges.
