The regular expression parser. Translates a regular expression read from a stream into a parse tree. (''accessing'' protocol). The tree can later be passed to a matcher initialization method. All other classes in this category implement the tree. Refer to their comments for any details.

Instance variables:
    input        <Stream> A stream with the regular expression being parsed.
    lookahead    <Character>!
