Converts numbers to alphabetical strings and back.

Because I don't like to use numbers in URL paths, this nodejs module converts them to an alphabetical string.

This is NOT a cryptographic module. Please don't use it as such.

This library is intended to convert numbers to characters and back for display only. Please use caution if storing the results as subsequent versions may change the character conversion sets.

Converts 11121314 to HAQhW.

E.g.: http://example.com/users/11121314 becomes http://example.com/users/HAQhW

var alphanum = require('alphanumbers');

var str = alphanum.toAlpha(11121314);
//str = HAQhW

var num = alphanum.toNumeric('HAQhW');
//num = 11121314

Includes the replaceAll utility function as found on http://stackoverflow.com/a/6714233/153083 but doesn't add it as a prototype method.

replaceAll: function(sourceString, findStr, replaceWithStr, ignoreCase)

var str = alphanum.replaceAll('x','x','xyz',false); 
// str = xyz

Fork and send pull request! Please observe the following:

• Pure alphabetical substitution is preferred.
• Any sort of statistical analysis for better number shorting much appreciated
• Additional unit tests wanted

Currently 125 tests are passing.
