Implemented basic external transform function
* "InputXSLT:transform" expects two input arguments and executes the given transformation into the given target file ** this function respresents a important step in the direction of making it possible to write an actual static site generator on top of InputXSLT using XSLT * added basic "transform" test case * updated README.md to include this new function
