Function for reading html data from the web.

[elinw]

Need to have a way to read a folder of html files Assume that the user has proper read permission. Maybe use rvest?

I think the way to approach this is to create an alternative version of read_documents_data that uses rvest and then takes the output and puts it into the correct format.

This is done at the command line, prior to importing the data into the project.
