[Description]
Gets the index of remaining factors of an expression.

[Explanation]
If <I>ptr</I> points to the <A HREF="$$LINK(Tags)">MUL_TAG</A>, which is a case when it
points to an expression of form <I>factor1</I>&nbsp;*&nbsp;<I>factor2</I>&nbsp;*&nbsp;<B>...</B>
(i.e. if the expression is a sum of simpler terms), remaining_factors_index returns the pointer
to the subexpression <I>term2</I>&nbsp;*&nbsp;<B>...</B> (i.e. to the remaining
factors of the expression). If <I>ptr</I> does not point to the
<A HREF="$$LINK(Tags)">MUL_TAG</A> (i.e. if the expression is not a product of simpler factors),
remaining_factors_index returns a pointer to a simple expression which
consists only of number 1.
<BR><BR>
<B>Note:</B> Expressions in internal canonic form have the most main factor shallowest, with less main factors
below that (see <A HREF="$$LINK(compare_expressions)">compare_expressions</A> for more info about "main"
ordering). Also, the lead factor of an internally-simplified product is never a product.
For example, remaining factors of <CODE>'(3*x^2)*y'</CODE> converted into canonic form
are <CODE>'3*y'</CODE>. By default, similar powers of the main variable are collected, so
remaining factor of <CODE>'x^2*y+x^2'</CODE> after conversion into canonic form is
<CODE>'y+1'</CODE>. Internally-simplified numeric denominator factors are combined with
numeric numerator factors into a fractional numeric factor. Non-numeric denominator
factors are internally simplified to be merged with numerator factors as negative powers.
See <A HREF="$$LINK(push_internal_simplify)">push_internal_simplify</A>
for more info about how to convert an expression into the internal canonic form.
