+// NOTE: I'm not comfortable with the wallet being global data and this high up
+// in the heirarchy, but there are 3 reasons for its current placement here:
+// 1) There are some important threading issues where it comes to the password
+// handling code, and a lot of it is done outside of the objects. 
+// 2) Different backends need access to the same wallet. so that it is not
+// opened multiple times.
+// 3) MainController is about the only thing that isn't deleted in between connection
+// attempts.
