Fixed bug in AtkinsonBoore2006Prime GMPE that only appeared for
VS30 < 760 m/s
First implementation of CAV filtering in oq-hazardlib:
- Added get_poes_cav method in GroundShakingIntensityModel base class.
- Added cav_min parameter in hazard_curves_poissonian function, and
changed gsim.get_poes call to gsim.get_poes_cav
First implementation of CAV filtering in oq-hazardlib (part 2).
Added gsim/cav.py, containing functions to compute the
CAV exceedance probability in function of PGA, magnitude,
and vs30, using the two-step approach based on an empirical
model of CAV in the U.S., as described in EPRI (2006).
