Pull request overview
This pull request adds a comprehensive C API for the GauXC library, enabling integration with C codebases and other languages that interface with C. The implementation wraps core GauXC C++ functionality including molecular structures, basis sets, integration grids, load balancing, and XC integrators.
Changes:
- Added C API bindings for core classes (Molecule, Atom, BasisSet, Shell, etc.)
- Implemented factory patterns for runtime environments, load balancers, molecular weights, and XC integrators
- Created C/C++ compatible enum definitions with mappings between C and C++ versions
- Added HDF5 I/O support for C API
- Refactored configuration headers to separate C and C++ concerns
