/**
 * Formats the number according to the 'format' string; adherses to the american number standard where a comma is inserted after every 3 digits.
 *  note: there should be only 1 contiguous number in the format, where a number consists of digits, period, and commas
 *        any other characters can be wrapped around this number, including '$', '%', or text
 *        examples (123456.789):
 *          '0' - (123456) show only digits, no precision
 *          '0.00' - (123456.78) show only digits, 2 precision
 *          '0.0000' - (123456.7890) show only digits, 4 precision
 *          '0,000' - (123,456) show comma and digits, no precision
 *          '0,000.00' - (123,456.78) show comma and digits, 2 precision
 *          '0,0.00' - (123,456.78) shortcut method, show comma and digits, 2 precision
 *
 * @method format
 * @param format {string} the way you would like to format this text
 * @return {string} the formatted number
