/* How connecting works
*
* 1.) The user right-clicks on a box and clicks "Connect To..."
*
* 2.) A line is created, and immediately connected to the box the user right-clicked on.
* 2a.) The Drawing Surface calls the line's Connect() function, passing the box.
* 2b.) The Drawing Surface then calls the box's Connect() function, passing the line.
* 2ba.) The box must choose which anchor point to connect the line to. It could ask for the location of the connected endpoint.
* OR
* the line could ask the box to pick an anchor point, passing a point (e.g. the current position of the cursor), so it can find the closest anchor point.
*
* OR OR
* The box could just pick a default anchor point (e.g. bottom), and then once both boxes have been connected, call a method to choose which anchor point
* to move the endpoint to.
*
* 3.) The user then clicks on a second box to finish the connection.
* 3a.) The Drawing Surface calls the line's Connect() function, passing the box.
* 3b.) The Drawing Surface then calls the box's Connect() function, passing the line.
* 3ba.) The box stores the line in a default anchor
*
* 4.) The Drawing surface, knowing that the connection has been made, calls the second box's FinishConnection() function.
* 4a.) The function asks the line in it's default anchor for the position of the far endpoint
* 4aa.) the box could pass it's default_anchor position to the line, which will then compare to the locations of it's endpoints.
* The line will then return the position of the endpoint connected to the other box.
* 4b.) The box then chooses which anchor point is closest to that far endpoint, moving the line into the appropriate List, and telling the line to move
* the endpoint to the new position.
*
* 5.) repeat step 4 but with the first box.
