 
Summary: Function: Bigebra:`&cco`  Clifford coproduct
Calling Sequence:
t1 = &cco(p1,i)
t1 = &cco(c1)
Parameters:
· p1 : a tensorpolynom (element of `type/tensorpolynom`) of rank not less than i in each factor
i : the slot number (first slot from the left is 1) on which the coproduct acts
· c1 : a Clifford polynom (element of one of these types: `type/clipolynom`, `type/climon`,
`type/clibasmon`)
Output:
· t1 : a tensor polynom
Global variables:
· BI_Id  set by make_BI_Id
· dim_V  the dimension of the onevector space V
WARNING:
The Clifford coproduct takes only one 'factor' (and one parameter), the infix form makes no sense
with this function and yields unpredictable nonsense.
Description:
· Like the Clifford product, Clifford coproduct needs a bilinear form defined on the base space of
the Grassmann algebra. In the case of the coproduct, this form is tied to coonevectors, so it is
