…s with a gridsearch of rotations+shifts.

I was torn about whether to add a feature to the existing Rigid algorithm or to create a new algorithm and leave that one untouched. I went with the latter, but I'm open to other ideas.

I think it's better as a separate algorithm. Nice work!

"""
`RigidGridStart(fixed, maxradians, rgridsz, mxshift; thresh_fac=(0.5)^ndims(fixed), thresh=nothing, SD = eye(ndims(fixed)), pid=1, kwargs...)`
initializes the `RigidGridStart` registration algorithm. This algorithm works much like `Rigid` except that instead of initializing with a
principle axis transformation it intializes with a grid search of rotations+shifts. Possible shifts are specified by `mxshift` while rotations

It seems the build is failing because it can't build CUDArt. I didn't change anything related to CUDArt in this PR. My memory may be incorrect but I believe in the past we intelligently skipped building CUDArt when building on Travis. Any idea what's changed?
