Test 1d

[MuawizChaudhary]

This PR adds a whole suite of tests for the Torch, Tensorflow, and Numpy backend primitives. Additionally, tests for scattering and tests for backend primitives are broken into two separate files. Perhaps we want to do something similar with frontend tests?

Additionally, some already existing backend functions have been modified to perform type checking, such as adding a complex check to the subsampling functions in the numpy and tensorflow backends.

[MuawizChaudhary]

we should really finish up the R2C pr first tho.

are we ready for merge?

[MuawizChaudhary]

Remove.

[janden]

Just add that blank line and it's ready for merge.

[MuawizChaudhary]

Added!

[eickenberg]

yup seems good to go to me

[janden]

Let's make sure the tests pass, then we're ready to merge.

[MuawizChaudhary]

The tests pass on my end. I can try changing the tolerance and see if that changes things

[MuawizChaudhary]

Looks like jenkins passes.

[janden]

Still failing on Travis. Can you increase the tolerance for that test? Also make sure to put a comment explaining why we need the increased tolerances.
