Making transpose function as a property

[ZAARAOUI999]

Hi Mr Andreas, I wanna share with you this small trick, it looks like not interesting but...
So, my idea is just to add @property before this function in the Tensor class:

@property
def T(self):
        return transpose(self)

So the user can get the transpose with just typing Tensor.T rather than Tensor.T()
Thanks.

Hi @ZAARAOUI999!

Thank you for your valuable idea - I didn't know that before.
