[Development] Notes from the Containers session from QtCS

Hi,

I meant "are candidates for marking as movable" ;-)

I think that people who care about QSharedDataPointer for optimizing
stuff should be able to understand the implications.

What about something like this:
"If your data class uses a
QSharedDataPointer/QExplicitlySharedDataPointer as the only member you
should consider marking your data class as a movable type (link to
Q_DECLARE_TYPEINFO) in order to improve performance when using Qt's
container classes."
