     * This is a simple utility to split strings.
     * The string is splitted following these rules (in the order):
     * <ul>
     * <li>If a single quote (') or a double quote (") is found at the start of the word, the split will
     * occour at the next quote or double quote
     * <li>Otherwise, the split occurres as soon as a space is found.
