Added db load ability (#106)

* Added db load ability, updated README

* Fixed spacing on multiplication

* Fixed double quotes

* Added double quotes to .db

* After reading the code, realized we can return here for .db extension, and let main handle loading the .db into archival memory.
Issue is that the final else was treating the db as a file and reading it in raw, causing issues.

* Removed .csv reference, not currently working.
