Create a way to read project data from a spread sheet

[elinw]

If someone has data in a spreadsheet or csv that maybe they got from an API, read that in so that each row is a document. This should be pretty easy, and we can suggest readxl as a package.

Essentially this would provide a different way to set up a project prior to launching the app.

We did this today by hand. This involves creating a data frame with the three correctly named columns.
So we need to read in the file and do the renames and selects. Then the file needs to be correctly named for the projec.

My solution is to use 'map()' to save each individual comment in a seperate .txt like this

directionsrlrs is the column name containing all comments.
Each comments is saved to a seperate .txt file in the documents/ subfolder. Each .txt files is named with the sequence number (row number).
