location of data used by the examples

[grlee77]

The following three examples currently refer to hard-coded file names which do not seem to exist in the repository:

recon_ismrmrd_dataset.py:
testdata.h5

recon_multi_reps.py:
tpat3_noise.h5
tpat3_data.h5

parallel_imaging_demo.py:
hansen_exercises2.mat

The generate_cartesian_shepp_logan_dataset.py example generates a testdata.h5 that works for recon_ismrmrd_dataset.py, but I was unable to find the data for the other two examples.

Maybe something like get_data.py from gadgetron could be set up to download these data if they are too large to store in the github repository itself? Or more simply, just give a link to the data location in a comment at the top of each of these examples.

These were examples that I did for an ISMRM tutorial. You can find some instructions, etc. here:

http://nbviewer.ipython.org/github/hansenms/ismrmrd_sunrise_notebooks/blob/master/Instructions.ipynb

Or here:

If somebody would like to set up resources in terms of files, etc. I would certainly support that, but so far I have not found the time.
