into a polynomial represented as an expression (first argument)
and vice-versa.
`simpolylist/2` - simplifies a polynomial represented as a list into
another polynomial as a list.
`simpoly/2` - simplifies a polynomial represented as an expression
as another polynomial as an expression.
`scalepoly/3` - multiplies a polynomial represented as an expression by a scalar
resulting in a second polynomial. The two first arguments are assumed to
be ground. The polynomial resulting from the sum is in simplified form.
`addpoly/3` - adds two polynomials as expressions resulting in a
third one. The two first arguments are assumed to be ground.
The polynomial resulting from the sum is in simplified form.
