matRad_listAllFiles

 matRad function to get all files in arbitrary deep subfolders
 
 call
   fileList = matRad_listAllFiles()
   fileList = matRad_listAllFiles(dirPath)
   fileList = matRad_listAllFiles(uiInput)

 input
   dirPath:        (optional) initial folder to start searching
   uiInput:        (optional) if userInteraction is wanted.
                   Use EITHER dirPath or uiInput

 output
   fileList:       Filelist

 Note
                   MATLAB has an internal recursion limit. If you want to
                   list a huge amount of files you may have to: 
                   >> % N = Number of allowed recursions
                   >> set(0,'RecursionLimit',N)
