fixed #60
When GLV is set to false (endomorphism not available) in the config file, the templates still generate code for some computations (ClearCofactorl(), IsInSubgroupl(), ScalarMul()) that use the endomorphism phi(). This PR fixes the problem.

When the GLV is set to false, the templates:

  • use mulWindowed() instead of mulGLV()
  • multiply by r for IsInSubGroup()
  • multiply by the cofactors for ClearCofactor() (for BW6 curves)
