Add Helper files

[bonimy]

Issue

A lot of the files from the archival Helper project are complete and usable in their current stage. It would be helpful to add them since they will get a lot of use.

Resolution

Some of the files are already fully documented and include unit tests. These can be added right away. Others are useful but lack documentation or unit tests. Those should be updated then added.

I should add the readme to this and it should be all done.
