"Same sheet" chartifacts #4
Description
Some chartifacts will be on the same literal piece of paper as others, if a buyer wants to buy the whole sheet and not split it up.
This might also allow them to choose to transfer some of the chartifacts without transferring ownership of the digital chart (for example, imagine a hand-written chart of the entire piece by a session musician who plays a killer solo over the B part - the owner may be willing to sell or give the A and C parts away, but want to keep the awesome solo chartifact).
So... not sure if this means we want to separately model the page? Or if we want some kind of data model that shows which chartifacts are linked by paper?
