DiracSimplify[expr] simplifies products of Dirac matrices in expr and expands non-commutative products. Double Lorentz indices and four vectors are contracted. The Dirac equation is applied. All DiracMatrix, DiracMatrix and DiracMatrix are moved to the right. The order of the other Dirac matrices is not changed.

This is a string of Dirac matrices in four dimensions.
This is a string of Dirac matrices in D dimensions.
By default is moved to the right.
Contrary to DiracTrick DiracSimplify does non-commutative expansion.
With the option DiracCanonical an alphabetic ordering is done.
Setting InsideDiracTrace->True assumes that a trace is still to be taken later on.
