allowing to read the new nifti TR pixdim field

allowing to read the new nifti convention that include the tr in the last pixdim field

[lmperry]

@JWinawer, @arokem, can you comment on whether or not you think this change will adversely affect "normal" usage?

[arokem]

I might be wrong, but I think that the danger lies mainly in places in
which previously there was an assumption that the variable pixdim does
not have the TR.

For example, lines of code like the following:

https://github.com/vistalab/vistasoft/blob/master/mrDiffusion/GUI/dtiFiberUI.m#L735

Might have to be rewritten to refer explicitly to pixdim(1:3), but I have
not run any of the tests, so I can't point to any particular failure.

Is niftiNi2Vista.m on the main path for all nifti reads? Seems so, from a
quick look.

i will try to check. one question: did you (or anyone) try running the
validation code? (mrvTest)

that would be a good start.
