Made symbols capable of containing chops, added an unfinished list error, and rearranged the code to pull all the reader macros into one place.
Moved the character lists closer to the reader macros, sorted as 01-9 rather than 1-90, and stopped using falsiness to test for end of stream.
Added some notes, and stopped using Array#forEach().
Added the MIT License, reorganized, and added a basis for macroexpansion.
