Class and Interface markup

Two new tags added for creating class diagram.

1. .class. tag to indicate a class object

2. .inf. tag to indicate an interface

Here is an example usage:

Minor changed to dot and bullet markup

A sequence of dots that is not followed by text is shown as:

· Number of consecutive dots <= 3 is shown as typed “.” , “..”, “…”

· Number of consecutive dots > 3 is now equivalent to .div. tag

A sequence of dots followed by text is still representing as bullet like before

. bullet 1

. bullet 2

.. incline bullet

… triple incline bullet
