First pass schema deducer code

[Mark Giffin <mark@markgiffin.com>]

I have put Don Day's first pass at a schema deducer here:

https://github.com/oasis-open/dita-lightweight/tree/master/schema-deducer

It's the PHP code and HTML that run this site:

http://ditax.ml/lwd/

This is the first effort at coming up with a tool that will read in a 
template file and output a schema like a DTD, W3C Schema, etc. Part of 
this is a simplified method to do DITA specializations.
