Implemented basic generation summary

* "summarize.xsl" processes the result-tree of "process.xsl" and outputs a basic plain-text summary
** the plain-text summary is returned as the sole result of calling "make.xsl"
* this approach should be easily extensible into i.e. a verbose version in the future
* unraveled "make.xsl" structure into separate variables
