If modules overlap, deleting one can clobber the other

Describe the bug
If modules overlap, deleting one can clobber the other

Application: Brain Simulator,

To Reproduce
Steps to reproduce the behavior:

1. Create network with ImageFile Module
2. Overlay ColorComponent module over a pixel of the picture area
3. Delete the ImageFile module
4. The ColorComponent module crashes because it relies on neuron settings which have been removed

Maybe we are having trouble here since the module literally occupy neurons rather than having their own "sub-network". If every module had its own network they would be truly independent.

Yes, this is also exactly the problem of dragging modules or selections across each other. It seems like this would be a big deal to fix but perhaps not.
