The resolve function now looks up symbols dynamically in the Fexl library linked with the executable. Any function named "type_X" is now automatically available as a function "X" in Fexl. Refactored the code so it's cleaner, faster, smaller, and with fewer inter-dependencies. The .bench2 test is about 6% faster.
