better documentation for Akkar Bommer 2010 GMPE
removed 'filter_sites_by_distance_to_rupture' method from point.py so that method in base class is used instead - which makes use of JB distance
updated tests
Merge pull request #140 from monellid/fix-rup-filter

Fix rupture distance filtering in Point and Area Source
Reverted change to distance computation
redefined SeismicSource as ParametricSeismicSource which extends a new BaseSeismicSource
renamed ProbabilisticRupture to ParametricProbabilisticRupture which extends a BaseProbabilisticRupture
removed  so that jb-based distance method in super class is used instead
updated tests
removed reference to PointSource.filter_sites_by_distance_to_rupture
made PointSource constructor accepting temporal occurrence model, and updated PointSource tests
updated AreaSource constructor to accept temporal occurrence model + updated tests
SimpleFaultSource now accepts a temporal occurrence model in the constructor + updated tests
ComplexFaultSource accept temporal occurrence model in the constructror + updated tests
CharacteristicFaultSource requires a temporal occurrence model in the constructor + updated tests
fixed disaggregation calculator
fixed PEER tests
fixed more tests for disaggregation and hazard curve calculator
