Evaluate the use of subcontainers

[intentor]

Consider the following scenario:

1. There's a main container with all common bindings;
2. There's a secondary container with all gameplay related bindings;
3. There's another secondary container with all store related bindings.

To prevent having to recreate all bindings from 1, it should be interesting to have some form of subcontainer in which 2 and 3 would inherit all bindings from 1.

Another idea is to make it easier to remove those subcontainers and all binding references they contain.

I can be useful for games with additive scenes.

A test case would be an always available container (destroyOnLoad = false) having all singletons and other containers using those singletons as injections througout their transient classes.
