- added Clifford contractions:
   gamma~mu*gamma~alpha*gamma~beta*gamma.mu
   gamma~mu*gamma~alpha*gamma~beta*gamma~delta*gamma.mu
- detection of free indices of the complete product in
  simplify_indexed_product() could go wrong if contractions resulted in
  composite expressions
ginac/clifford.cpp
ginac/indexed.cpp
