150 right shape

[Lenoush]

answer to #150

Basically, every time you call op and adj_op, make sure the input image is of the shape , which was provided during initialization.

• create a function that checks whether the shape of the image (in this case, the data) == self.shape (from init)
• call it when op
• test this function
• call it when adj_op

The CPU-based backend is handled differently

I think we dont need to send the shape in. Also, we might need to be careful and check only last 2 or 3 dimensions (in case we have batches)

[paquiteau]

All CPU based backend should rather be handled via the FourierOperatorCPU.op.

Otherwise this LGTM

[chaithyagr]

Thank you. I think the codes are a bit confusing and some things can be refactored

[chaithyagr]

Almost there, getting nitpicky now, but a couple of important changes also.

[paquiteau]

Some suggestions, otherwise this seems good.
