orgnames.R will eventually be a function "orgnames" that will return a vector of org names from input columns:

orgnames <- function(title, comment.text, attachment.text){
...
}

Ideally, other variables applying the codebook, like org.comment should be created in separate scripts, but we may need to do several at a time if there is no one sequence in which to define them.

Defining congress will also need its own function in its own script.

implemented in org_name.R (used in comment_coding_sheets.R and elsewhere), but there is still more work to do. More notes in #3.
