Add timer:sleep(100) after each 10 modules trace pattern and remove dialyzer warnings
When setting trace pattern for many modules the system will quite unresponsive and thus we have added a timer:sleep(100) after every 10 modules to set trace patterns for. Code has also been change in order to get rid of dialyzer warnings. I.e removal of dead code.

--module(inviso_tool).
-
-
-%% This is the inviso tool, which is a tool using the inviso trace application.
-%% It is developed to make tracing using trace cases possible in an environment
-%% of distributed Erlang nodes.
-%% A current restriction is that the Erlang nodes are supposed to have the same
-%% code. This since inviso tool can at this point not handle subsets of nodes.
-%% Instead all participating Erlang nodes are treated the same.
-%%
-%% The main functionality of the inviso tool are:
-%%
-%% (1) Handles start and stop of tracing at participating nodes.
-%% (2) Interprets trace-case files at a distributed network level.
-%% (The inviso runtime component is responsible for interpreting
-%% trace cases at a local level, if run in an autostart).
-%% (3) Keeps a command history log from which:
-%% (a) Sequences easily can be repeated.
-%% (b) Autostart configuration files can be created (understood by the
-%% default inviso autostart mechanism).
-%% (4) Performs reactivation in case tracing is suspended (manually or by
-%% an overload mechanism).
-%% (5) Can reconnect crashed nodes and by using the history bringing them
-%% up to speed.
-
-%% Distributed Erlang
-%% ------------------
-%% Inviso is built to run in a distributed environment.
-%% The inviso tool can also be used in a non distributed environment.
-
-%% Short description
-%% -----------------
-%% Start-up of the inviso tool
-%% During the start-up of the tool, the tool starts runtime components at
-%% all participating nodes. A runtime component can already be running at
-%% a particular node and will then simply be adopted.
-%%
-%% Session
-%% A session is said to start when tracing is initiated, and ends when
-%% made to stop by the user. When a session is stopped, tracing is stopped
-%% at all participating nodes. Note that participating nodes may come and
-%% go though the time-frame of a session. That means that if a node is
-%% reconnected it may resume its tracing in the current session through
-%% a 'restart_session'. A runtime component that is already tracing at the
-%% time start-session will simply be part of the session without its
-%% ingoing tracing being changed.
-%%
-%% Reactivation
-%% A node that is suspended can be reactivated to resume tracing. Note that
-%% tracing has in this situation never been stopped at the node in question.
-%% The inviso tool resumes the node and applies the history to it.
-%%
-%% Reconnect
-%% A node that is "down" from the inviso tool's perspective can be
-%% reconnected. During reconnection the tool restarts the runtime component
-%% at that node but does not (re)initiate tracing. The latter is called
-%% restart_session and must be done explicitly, unless the node in question
-%% is in fact already tracing. If the node is already tracing (due to an autostart
-%% for instance), it automatically becomes part of the ongoing session (if
-%% there is an ongoing session).
-%%
-%% Restart Session
-%% A node that has been down and has been reconnected can be made to
-%% initialize and resume its tracing. This is done by starting the session
-%% at the node in question and redoing the current history.
-
-%% Trace files within a session
-%% Since it is possible to init-tracing (from an inviso perspective) several
-%% times within the same session, a session may leave several trace log files
-%% behind. This must be resolved by the tracer data generator function
-%% (user supplied) by marking filenames in a chronological order but still
-%% making them possible to identify as part of the same session
