Import function for files in FAMOS format

Three functions to map & load all or individual signals from a measurement file in FAMOS format.

FAMOSconnect(filename)
reads a (MARC generated) FAMOS file. It returns a struct that contains information about the stored signals and memory-map links to the actual data. No actual data is loaded yet. Thus there is no memory based limitation to length of source file.

FAMOSload(map,signal)
loads specific signals from a map struct provided by FAMOSconnect.

FAMOSimport(filename)
opens (MARC generated) FAMOS files and imports all signals.
