HClass returns the H class of the element s in the monoid M.

    gap> M:= Monoid( Transformation( [ 2, 1, 2 ] ),
    > Transformation( [ 1, 2, 2 ] ) );;
    gap> M.name:= "M";;
    gap> HClass( M, Transformation( [ 1, 2, 2 ] ) );
    HClass( M, Transformation( [ 1, 2, 2 ] ) ) 

The H class of s in M is the intersection of the R class of s in M and the L class of s in M (see RClass and LClass).
