numeric and alphanumeric formatters?

[arisi]

Hello,

nice work here -- but your web page mentions numeric formatter, and that is not included in the git source... just wondering if it an oversight, or should I write it ?

surely they are needed by almost anyone making fixed records.

I was initially planning on including a numeric formatter, but realized it may be more interest to let developers write their own. From experience, different specifications format numeric slightly differently, in particular when it comes to negative values.

For example, should "7" be formatted as "007", "+007", "007+", " 7". I'm not opposed to adding common formatters with descriptive enough names however if you want.
