Andrew D. Lewis's Mathematica programs

1. Affine: Some affine differential geometry functions.
2. Constraints: There are some functions here to do things for constrained mechanical systems in the affine connection framework.
3. Coordinates: There are a (very) few functions for doing coordinate changes for tensors.
4. InnerProduct: Some basic operations for inner products spaces.
5. SimpleSystems: Simple mechanical systems with symmetry.
