- merged some local changes (avoid using deprecated APIs)
- the xcode project has been civilized
(stuff was messed up a bit by the flowmixer branch and new files were in
weird locations)
NOTE:
this is still a work in progress and all functionalities still need
testing. Something could have been messed up by mergin my local changes
with flowmixer branch
- Separating view logic from the real layer implementations
(so layers can be created programmatically and associated to a
view only if/when necessary)
- Separating the c++ glue classes from their related cocoa implementations
