Expand description

Calculator library for evaluating freehand mathematical expressions.

The general workflow goes like this:

Create a Context: a reusable type which contains expression history.

This type is parametrized by the numeric type which all calculations will use.
Parse an ast::Expr with ast::parser::ExprParser.
Evaluate that expression with Context::evaluate.

You can freely modify the parsed expression; the types in ast are all public.

To enable calculation based on your custom numeric type, just impl types::Calcable for your type.
