Version 0.1.0

Basic Lisp programming can be done easily. Manual is almost finished.

Things left to do:

• Bad error handling, just prints to stderr.
• No cons pair support. Only simple linked lists of expressions, cdr is always a list.
• Bad memory management; nothing is passed by reference, instead everything is duplicated. No garbage collection. Could use a pool allocator.
• No tail-call optimization (see README).
• No proper closures (see README).
