Timing of 3D image reconstruction

Hi Jonathan,

I am Huihuo, working with Yi to optimize your code to run on ALCF machine.

I quickly checked the timing of
This is the timing of 3D/ASD_tv.py.

In the current implementation TV minimization took majority of the time. We suggest to use C++ code for the TV part.

The other issue is the definition of recon. It was defined as,
recon = np.zeros([Nslice, Nray, Nray], dtype=np.float32)
should it be recon = np.zeros([Nray, Nray, Nslice], dtype=np.float32) instead?

rename ctvlib::recon to ART

The function name ctvlib::recon is too general.
Better to rename it to ART as we will implement other algorithms in the future.
