Data Format Manager

[Randy Merrill]

Use an application manager singleton for formatting data. Allow for ability add multiple and custom formatters.

Would have a addFormatter(formatter) that would be added to an internal array of formatters.

When formatting is needed, the last formatter added with a matching function will be used to format the value. (LIFO)

For example, can use a formatPhoneUS(value, options) call to format a phone number in the US format. This would search the formatters for a function called phoneUS and call it with the arguments provided.
