Eric - a calculator

I wrote this program partly to scratch an itch (I've been failing to find a calculator utility with just the right feature set for years), but also as an exercise to help me learn the C# programming language and .NET framework classes.

Eric features:

• simple, lightweight commandline calculator
• define your own functions, including recursive ones
• floating point, integer, binary, and complex operators
• work in any number base
• interactive line editor with input history and undo/redo
• save function definitions to text files
• powerful graph display window
• watch window for spreadsheet style numeric exploration
