Update of /home/cvs/GiNaC/ginac

Modified Files:
	indexed.cpp 
Log Message:
simplify_indexed() will re-expand the expression and re-run the
simplification if a contraction in a product resulted in a factor that
is a sum or a product itself; so e.g. gamma~mu*gamma~nu*gamma.nu*gamma.mu
will return dim^2*ONE without having to run simplify_indexed() twice
