[F&E]: SingleObservationSet check for duplicate observations

[jo11he]

Description:

Some ODF files (in the context of the cassini mission) result in duplicate observations (same epoch, same value) within the same SingleObservationSet. There could be a check (with user control) to eliminate these duplicates.

Suggestions for implementation:

Define a member function that identifies duplicates and using the existing eraseDuplicates by index member functions of SingleObservationSet removes them. This function should be called in the constructor, toggled by a boolean in the constructor signature. The boolean should default to false (no elimination of duplicates) to avoid inconsistencies between transfer of set data from old to new sets like in e.g. observation set splits.

Instead, I propose to use a boolean on the createOdfObservedObservationCollectionFromFile signature that connects to the first call of the SingleObservationSet constructor, which eliminates duplicates (if user wishes) right at the first creation of the ObservationCollection.

I am working on this already.
