Release v1.1 · cako/curvelets

What's Changed

Simplified UDCT Construction - The PyTorch UDCT class now uses simplified construction via num_scales and wedges_per_direction parameters, with optional angular_wedges_config. Window overlap is now auto-computed, and parameter/window initialization has been refactored for better usability.
Tensor Migration Support - Added UDCT.apply_to_tensors and UDCTModule._apply methods, enabling proper tensor migration so .to(), .half(), .float(), and .double() methods now correctly propagate to internal windows and ratios.
New MNIST Classification Example - Added examples/plot_10_udct_mnist.py, a complete MNIST classifier using UDCTModule as a feature extractor. The example includes:
- Training and test loss/accuracy curves
- t-SNE visualization of curvelet features
- Misclassification analysis with worst-case examples
- Demonstrates how curvelet coefficients can replace traditional convolutional layers
Modernized Autograd Bridge - Updated _UDCTFunction to use setup_context for modern PyTorch compatibility and enabled functorch vmap compatibility for efficient batch processing.
Enhanced Type System - Introduced _from_sparse helper to densify windows, updated typing to include MUDCTCoefficients, and preserved monogenic placeholders (NotImplemented in torch).

Formatting - Minor wording and formatting tweaks to Credits sections

Full details: #46 by @cako

New Test Coverage - Added numpy↔torch UDCT parity tests, struct/vect round-trip tests, and dtype-transfer tests for UDCTModule
Configuration Updates - Updated .gitignore to ignore data/ directory, added mypy ignores for torchvision.* and sklearn.* imports

Streamlined Examples - Cleaned up unnecessary comments and results sections in example files to improve readability
