Deprecated. in favor of attoparsec

ParserFunction provides utilities for parsing and evaluating mathematical expressions. The central parsing function in this package is stringToExpr, which parses an expression (as a string) and returns an expression tree of type Expr (or nothing if the string is malformed). Expressions can be evaluated using the function evaluateExpression. Examples of these functions can be found by viewing the source code for this package.
