Currently, marks spreadsheets require columns to be created and cells to be updated through either the UI or CSV uploads, and data to be obtained through downloading CSVs. It would be nice if similar actions could be done through an API route as well, such as:

• Creating a new column
• Updating a cell given the column name, utorID, and a grade
• Retrieving the data from a marks spreadsheet (the entire spreadsheet itself, and/or a particular cell)
