I want to maintain a list of two-dimensional points and store, at list 
level, the min and max values for x and y. 

The minx/maxx/miny/maxy should be updated as each point is pushed onto 
the list.

The following works, but it's probably not leveraging Ruby:


def add_point( p )
   @points.push(p)
    if !@minx || @minx > p.x
        @minx=p.x
    end
    if ....

Thanks in advance.
