Should make some warning message. I ran this from the build directory
like:
../bin/dplot ../../trace.dat
and it did nothing. But if I ran it from the trace-cmd.git repo as
kernel-shark-qt/bin/dplot trace.dat
Then it did something. We need to make it work when called from
anywhere with a path to any trace.dat file. And give some kind of
message if no parameter is passed in.
Hmm, we should also probably make a separate directory for example
programs. Perhaps have a "demo" directory for these?
