This app reads all .fxg files from a given directory
Applies a given scalefactor to each first level child node in the fxg file
i.e. if the scalefactor is 2, it will add the attributes scaleX="2" scaleY="2" to each first level child node
Also applies scale factor to the Graphic object's viewWidth, viewHeight, scaleGridLeft, scaleGridRight, scaleGridBottom and scaleGridTop properties
