findGrade -- Find which graded piece of the algebra an element is in

Description

Let's build a 7-graded algebra and find the grade for several elements

i1 : extensionAlg = exteriorExtension(3, 7);
 
i2 : E = extensionAlg.appendage;
 
i3 : extensionAlg.findGrade (E_0*E_1)

o3 = 3
 
i4 : extensionAlg.findGrade (E_0*E_1*E_2*E_3)

o4 = 6

For the programmer

The object findGrade is a symbol.
