One to one Assignment for Association

[orosoman-dstl]

Created a new CompoundTimeRange class, a container class for TimeRange. This allows much greater flexibility for association objects, for example to associate two objects between the ranges [a,b] and [c,d] in a single TimeRangeAssociation.

New additions were made to the AssociationSet class mainly to reflect these changes.

The last main change was the new multidimensional_deconfliction algorithm. This is a very rudimentary but hopefully functional algorithm to ensure an AssociationSet has no associations that conflict - we can't have two different associations involving the same object at any given time. The algorithm is very basic, simply using the total length of an association as a proxy for strength of association, but I believe the groundwork has been laid to quickly implement something more advanced much more easily now.

So TimeRange/s now inherits from Interval/s. I had to make a few changes to the latter classes due to a few edge cases not being accounted for - eg interval.isdisjoint(interval) was returning True, which is of course incorrect. I also changed the attribute names for both classes to "start" and "end", a good compromise hopefully between an implication of chronology for TimeRange/s, while still keeping it more generic for Interval/s. There may be further room to combine the classes - I will review tomorrow.
