The implementation of IGslSvc interface.
The Gsl Service is teh service which perform intelligent error handling for GSL (GNU Scientific Library)
It provides a choice between different "Error Handling Policies"
Current implementation supports the several "error handling policies", which are driven by "ErrorPolicy" property of class GslSvc:
