You can now define structures in an enumeration
Now the function returns an array with the cords
Removed old defect test code
Now Blocks can't be used twice in a multi block structure.
Forgot to replace that var
Added an interface for hull blocks
Added a class for the multi block controller
Added the block class for the controller blocks
Added an method to set the controller
Added an test block

When mine craft crashes, the structure was right.
