splitModule :: MonadClean m => ModuleName -> m ()

Split each of a module's declarations into a new module. Update the imports of all the modules in the moduVerse to reflect the split. For example, if you have a module like

 module Start (a, b, (.+.)) where
 import
 a = 1 + a
 b = 2
 c = 3
 c' = 4
 (.+.) = b + c

After running splitModule the Start module will be gone. The a and b symbols will be in new modules named Start.A and Start.B. Because they were not exported by Start, the c and c' symbols will both be in a new module named Start.Internal.C. And the .+. symbol will be in a module named Start.OtherSymbols. Note that this module needs to import new Start.A and Start.Internal.C modules.

If we had imported and then re-exported a symbol in Start it would go into a module named Start.ReExported. Any instance declarations would go into Start.Instances.
