First commit of _InputXSLT_
* quick and dirty proof-of-concept for adding plain-file access to XSLT
** based on Apache Xalan XSLT processor
* The idea is to create something like a static counterpart to Symphony CMS
* Adding functions to XSLT for file system, plain file and binary file (read)-access
* This project aims to test how such functionality can be integrated into XSLT
** if it works it could be developed into a nice static content transformation system
* Contrary to the popular opinion I actually like XML and XSLT when used responsibly
