Index -- Optional input for idealizer

Description

This option allows the user to select the starting index for the new variables added in computing Hom(J,J) as a ring. The default value is 0 and is what most users will use. The option is needed for the iteration implemented in integralClosure.

Functions with optional argument named Index:

idealizer(...,Index=>...) -- Sets the starting index on the new variables used to build the endomorphism ring Hom(J,J)
ringFromFractions(...,Index=>...) -- see ringFromFractions -- find presentation for f.g. ring

For the programmer

The object Index is a symbol.
