I am writing a preliminary class to represent Holonomic Function. Link
<http://paste.ofcode.org/jNB29mns5iYuP3LfDaC8g5>
I need to know if I am going in the right direction or should I use some
different approach. I have question regarding printing of Holonomic
Functions, How can I add pretty printing and other methods for this class?
Or is the `def __repr__` method sufficient?
Also, In the class DifferentialOperator I have implemented the
multiplication rule i.e Dx*a = a*Dx + Derivative(a). e.g.
>>> Dx = symbols('Dx')
>>> p =DifferentialOperator(Dx-1)
>>> q =DifferentialOperator(x*Dx+1)
>>> p*q
2
Dx ⋅x - Dx⋅x + 2⋅Dx - 1
which should return:
x*Dx^2 + (-x + 2)*Dx - 1
The problem is that `Dx` is getting printed before `x`, which is wrong in
this case due to non-commutativity. What should I do in order to get `x`
printed before `Dx`?
I also tried defining the holonomic function class by inheriting from
Sympy's `Function` class, but I keep getting this error. Link
<http://paste.ofcode.org/SyX4ZD3shEc2HuaQSiatF2>. Also if I use this
approach then should I override different operations e.g. __add__ in our
class or we have to do it in any other way?
