Notes for Slide 06
Here is the same example with color used to show
that there is an if-else-endif block nested inside
of another if-else-endif block which is in turn
nested inside of a third if-else-endif block.
It is common to say that one block in "inside" the
other, or that one block "belongs to" the other.
