v0.3.0

This release includes a few enhancements to bt (as well as bug fixes) and the addition of a shape tool for compiling AppleSoft shape tables called st.

bt includes new optimizations:

• shorten-variable-names - Ensure all variables are 1 or 2 characters long;
• extract-constant-values - Assign all constant values first.

This project is split into three components:

• A Java API. See the README for an overview.
• A BASIC tokenizer (bt) command-line tool. See the README for tool usage examples.
• A Shape Table (st) command-line tool. See the README.
