Add CSaveEnv, optimize CAnd, make it prettier
...
CSaveEnv is a special constraint that indicates that the current
environment should be saved for later use.
(/\) now optimizes away arguments that are already CTrue.

Get the solver working on basic programs. It outputs pretty types for the
...
variables in the program. Need to test further and start doing some benchmarking.

Convert source-syntax types into type-checker types and print them
with pretty type variables.
Generate constraints for let-expressions using type annotations.
Build test function to turn strings into type constraints.
