dp_homo()
makes a copy of dpoly, extends
the length of the exponent vector of each term t in the copy by 1,
and sets the value of the newly appended
component to d-deg(t)
, where d is the total
degree of dpoly.
dp_dehomo()
make a copy of dpoly and removes the last component
of each terms in the copy.
hgr()
etc.
