+- On the left are the claases of the system. Next idea is to have hover info about them.
+- Middle is in three sections of source, only last really working
+- last section, current block with current instruction highlighted
+- step (next) button for single stepping
+- bottom row are the registers. If the register hold an object the variables are shown.

+So lots to do, but a good start.

 - single step debugging of the register machine level (as close to arm as need be)
