A ridefile reader for Polar .srd format files. The code is
largely based upon code from the "s710" project.
Since "s710" is dependant upon GD and a number of deployment tools
and the fact that the code hasn't changed since May 2007 the
workout code has been included directly into the SrdRideFile.h
and SrdRideFile.cpp source files.
2 sample SRD files have been included in the test/rides directory
which were kindly supplied by Ian Charles.
