Warnings about ott

[ilent2]

Should also be looked at for 1.4.
Matlab's warning reference page: https://au.mathworks.com/help/matlab/ref/warning.html
Is there an option for displaying a warning once per session, or once per function call? Would we have to implement a check ourselves whenever we are calling functions multiple times?

[AStilg]

I don't think it matters as it will display the warning every time matlab is opened. It can be an instruction that the warnings will silence after one time per matlab session (if we don't have enough control)

[ilent2]

Rather than writing conditions around the individual warnings, we could overload the warning function (and in 1.4 use a function called ott.warning) which checks if a warning has already been displayed.

[AStilg]

Pursuant to previous, octave is very obtuse in the way it treats warnings and doesn't display which file produces the warning. I suggest that the file name is introduced into warnings somewhere. E.g. replacing "This file..." with "xxx.m..."

I've just pushed dff474d which should make warnings less intrusive. Not sure if it is the cleanest solution. Any better suggestions or should we go with this for now?
