Consolidate definitions to use TensorProtocol

[philipce]

Description of Changes

Prior to the creation of the TensorProtocol--to which Vector, Matrix, and Tensor all conform--various functions were implemented and overloaded to accept all 3. This duplication is not ideal so these changes consolidate the function definitions into a genericized version.

Resolves

• Genericize functions to accept TensorProtocol as parameter

Thanks for looking at this! There are a handful of other functions that need this same change that I'll just put on this PR. Usually I use the WIP (work in progress) label to indicate it's not ready, and stick 'reviewable' on it when it is
