getXRDML() - function to load xrdml data from Panalytical diffractometers using the XOP XMLutils

It creates a folder for each xrdml-file read. The foldername will be the xrdml-filename in lower case letters without the fileextension. The intensities are loaded into waves called 'intensities##' stored in the folder /XMLutil/XRD/'filename'.
It can also handle mutiple (repeated) scans in one xrdml-file by assigning a number '##' to each intensities wave. It also reads the scan comments and additional information about each scan in the file like scannumber, start-,endtime, start-,endposition, measurement program and so on and stores them in a note to each intensities wave.
I am grateful to andyfaff for helping me putting his XMLutils to use with the xrdml files and for reviewing this snippet.
