Several improvements:
 - Replace MFReaderError with regular exceptions, and isolate exceptions
   in a try block that preserves the trace, and shows the position in
   the file
 - Use logger for showing messages
 - Start of HDF5 support from GMS, plenty more work needed
 - Add ASP package reference
 - Add reference to GMS 10 tutorials to reading tests
