Create Figures (graph windows).
FIGURE, by itself, opens a new Figure (graph window), and returns
an integer handle.
FIGURE(H) makes the H'th Figure the current Figure for
subsequent plotting commands. If Figure H does not exist, a new
one is created using the first available Figure handle.
GCF returns the handle to the current figure.
Execute GET (H) to see a list of figure object properties and
their current values. Execute SET (H) to see a list of figure
object properties and legal property values.
