Plot fake profile for non-sample dives

Browse source 
Right now it just plots something ridiculous, the code is really just
meant to be an example.  We migth be able to plot a traditional
staircase plot and make it look somewhat saner by taking mean depth into
account (if it exists).

Right now it just plots a (skewed) rectangular dive profile using the
max depth and total time. Which is obviously insane.
