Crate calc 

Calculator library for evaluating freehand mathematical expressions.

The general workflow goes like this:

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

• 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.
