v1.1.0

• Move TUI backend from termbox to https://github.com/peterh/liner
• Add --eval flag for programmatic usecases
• Convert to go modules
• Move core functions into time library

WARNING: TimeCalc has some issues. Multiplication seems broken in some cases, and full order of operations support remains NOT functional. I need to refactor the compiler at some point to address these issues.

v1.0.0 - First Release
