Vijay Janapa Reddi 04cbc65724 Fix training pipeline: Parameter class, Variable.sum(), gradient handling
Major fixes for complete training pipeline functionality:

Core Components Fixed:
- Parameter class: Now wraps Variables with requires_grad=True for proper gradient tracking
- Variable.sum(): Essential for scalar loss computation from multi-element tensors
- Gradient handling: Fixed memoryview issues in autograd and activations
- Tensor indexing: Added __getitem__ support for weight inspection

Training Results:
- XOR learning: 100% accuracy (4/4) - network successfully learns XOR function
- Linear regression: Weight=1.991 (target=2.0), Bias=0.980 (target=1.0)
- Integration tests: 21/22 passing (95.5% success rate)
- Module tests: All individual modules passing
- General functionality: 4/5 tests passing with core training working

Technical Details:
- Fixed gradient data access patterns throughout activations.py
- Added safe memoryview handling in Variable.backward()
- Implemented proper Parameter-Variable delegation
- Added Tensor subscripting for debugging access
