P = PROBEAVERFF(F, RECT), where F is an array of scalar fields, and RECT
a rectangle in the form [X1, Y1, X2, Y2], returns the time series of
the field averaged over the rectangle. RECT is specified in physical
units (eg., in mm). P is an array of size LENGTH(F).
P = PROBEAVERFF(F) allows the user to select a rectangle using the mouse.
[UX, UY] = PROBEAVERFF(...) or [UX, UY, UZ] = PROBEAVERFF(...) does
the same for a 2-component or a 3-component array of vector fields.
By default, NaNs are ignored. Modify the internal variable 'method' to
change this behaviour.
