There's an opportunity here to bikeshed about names of internal aliases... just in case things can be improved for more clarity. I was not very creative. |

It turns out that for non-triangular sparse matrices,
getcolptr, which can be easily computed from the parent array, is not used. But all the otherget*functions don't require a unit range as the second slicing argumnet in column views, so the fast multiplication kernels also apply to that situation.Fixes #475.
