public class NumberParser
extends Object

A helper class that parses Numbers out of Strings in a lenient manner.

No method will throw any sort of Exception when parsing a string. All methods accept any Java String or null as legal input, if the input is non null, whitespace will be trimmed first, and then parsing will be attempted.

:TODO: Add Integer, Float, and Double methods as needed.
