Clearly mark type of observation

[sergiopoppi]

Schedule must show which type of observation is generated : MAP, cross etc. From target and file must be written in the schedule

the ScanMode.__str__ method can be used for this purpose. This is using the class name.

I can see that I had defined the self.name attribute in the ScanMode class but that is never overwritten by the subclasses, most likely my mistake. It should be easy to add proper names for every scan mode and define a new method in the ScanMode class if needed that returns the required representation.
