#1 Extend documentation

[Stephan Lehmke]

The current state of the documentation has
been criticized as being too terse and address
mostly LaTeX experts.

This intentional to some degree, as the pre-alpha
releases were meant only for LaTeX pros anyway.

But as the alpha release is now out and available
to a much larger public, it is important to
improve the documentation, especially to augment
it with lots of basic examples demonstrating
the different commands and parameters.

At the same time, the obsolete `full demo' should
be eradicated and replaced by a `screen version'
of the manual demonstrating the effects from the
examples given therein.
