DESCRIPTION

	continuous statistics keeps a running tally of the biggest and
smallest numbers to come through its input ports.  The text string parameters
will update each time a smaller of larger value comes through one of its ports.

	If the reset button is turned on, then the running tally is reset to
have to current minimum or maximum.

EXAMPLES

	If on one execution the module received 0.020 and -0.020, and at the
next execution the module receives 0.039 and -0.05, then the string parameters
will display 0.039 and -0.020.

APPLICATION
	
        If you have a time series of data, you want to find out the absolute
minimum and maximum of the data values over time, so that you can set up
a colormap accordingly.  This module allows that capability, as it will continue
to store minimum and maximum values as the data changes.
