[Insight-developers] Split ImageFileReader/Writer Factory And Factoryless- crazy idea 2

[Xiaoxiao Liu]

This sounds like a great quick solution, which solves the
dependency issues for the modularization and provides s the capability of
 IO format selection to the user at the same time.

I wouldn't worry about the cmake variables that much. There will be a cmake
variable for each module (about 90 modules) in the modularized version of
ITK anyways. We do need
a better grouping mechanism to make it user friendly.
