subsurface/profile-widget/divehandler.cpp
Berthold Stoeger 396758d489 profile use unique_ptr to manage dive handler objects
Instead of manually deleting them (and the gases). Currently
there is only one point where these are deleted, but if
we implement proper Qt model/view semantics, this makes things
less headachy.
