-%% Description:
-%% The runtime component of the trace tool Inviso.

-
-%% Inviso Session Handler.
-%% This is the code for the session handler process. Its purpose is that we have
-%% one session handler process for each trace session started through the
-%% start_session inviso tool API. The session handler process is responsible for:
-%%
-%% -Knowing the state/status of all participating runtime components.
-%% -Keeping storage of all tracerdata all our participants have used. This means
-%%  also to find out the tracerdata of runtime components connecting by them
-%%  selves.
-%%
-%% STORAGE STRATEGY
-%% ----------------
-%% The local information storage can be changed by two things. Either by executing
-%% commands issued through our APIs. Or by receiving trace_event from the control
-%% component. When we execute commands, a corresponding event will also follow.
-%% Meaning that in those situations we are informed twice.
-%% A simple strategy could be to wait for the event even when doing the changes
-%% to the runtime components our self (through commands). But that may result in
-%% a small time frame where someone might do yet another command and failing
-%% because the local information storage is not uptodate as it would have been
-%% expected to be. Therefore we always update the local storage when making changes
-%% to a runtime component our selves. There will eventually be a double update
-%% through an incoming event. But the storage must coop with that, preventing
-%% inconsitancies to happend. An example of a strategy is that the tracerdata table
-%% is a bag, not allowing for double entries of the same kind. Therefore a double
-%% update is harmless there.
