- * This function is intended to extend the String object and provide
- * an String.format API for string formatting.
- * It has to be set up using String.prototype.format = Format.format;
- * Usage:
- * "somestring %s %d".format('hello', 5);
- * It supports %s, %d, %x and %f, for %f it also support precisions like
- * "%.2f".format(1.526). All specifiers can be prefixed with a minimum
- * field width, e.g. "%5s".format("foo"). Unless the width is prefixed
- * with '0', the formatted string will be padded with spaces.
