Time Blocking Table - Tools (Bulk category paint, copy and paste cell tool, )

[Cknutson100]

Create and implement a bulk paint tool that will allow users to quickly categorize cells when they have finished implementing their time block tables.

1/19/22: Will need a global state (context) that says your clicker is using the bulk paint tool. Once you click on a cell it will check to see if that cell has a category and assign the color of that category to the bulk painter.

1/23/22: Want to also add in a copy & paste tool, because people will often have the same cells many days in a row and it should be easy for them to copy and paste stuff from one day to the next with all the information moving over.

Probably see #77 first. Especially before copy paste.

Probably don't need this before launch, because we can individually categorize cells.
