     * Produce a sanitized name that fits our standards for likely to work.

     * Java classes have a wider range of names that are technically allowed
     * (supposedly any Unicode name) than what we support. The reason for
     * going more narrow is to avoid situations with text encodings and
     * converting during the process of moving files between operating
     * systems, i.e. uploading from a Windows machine to a Linux server,
     * or reading a FAT32 partition in OS X and using a thumb drive.
     * <p/>
     * This helper function replaces everything but A-Z, a-z, and 0-9 with
     * underscores. Also disallows starting the sketch name with a digit.
