Title: As2008

This pr implements the Abrahamson and Silva 2008 GMPE. The class implements the equations as described in the original paper and also the errata available on line (http://peer.berkeley.edu/products/abrahamson-silva_nga_report_files/
AS08_NGA_errata.pdf). This class does not implement the 'constant displacement model' because no valid test data could be generated for this case.

Test data have been generated using the Fortran implementation of Dave Boore (http://www.daveboore.com/software_online.html) modified to not take into account the 'constant displacement model'
