#4 Support for bottom-up design

[Paul Pettersson]

Currently, IDE supports only strict top-down modelling/design. We need to support bottom-up (and mixture of top-down and bottom-up) modelling/design.

E.g. it is impossible to first model some components, then decide to encapsulate them into a composite component. (it is possible to first make the composite component, then model the "inside" components).

This is a general problem. Not only related to the existing of a functioning repository.
