//So the whole point of the following two functions is that they provide

//Now, you actually *can* give them arguments ranging from -1 to 4 
//representing the outer neighbors.
//This is actually quite helpful and allows you to write the electronfinding
//algorithm in the same form no matter what tower you're centered on.

//As a reminder i is row and j is column, just like matrices.

//The following list of give and set functions are the core

//what would be the appropriate neighbor information so that you can
//use the set methods on the other region in order to set the neighbor
//information.  For example, r0:crate 0 card 0 region 0 is the northern
//neighbor of r1:crate 0 card 1 region 0.  Then to set the northern
//neighbor information you call r1.setNorthEt(r0.getNorthEt())
//That's why it's give insted of get.  It doesn't return the region's
//northern neighbor information, it returns what would be its southern
//neighbor's northern neighbor information.
