Example:

is_blue = AttrTrigger.new( :color => :blue )

# Matches only an event which has EITHER:
#  1. #color == :red, OR
#  2. #color == :blue
is_red_or_blue = OrTrigger.new( is_red, is_blue )

# More complex example with nested logic triggers:

changed = InstanceOfTrigger.new( ColorChanged )

changed_to_red_or_blue = 
  AndTrigger.new( changed, is_red_or_blue )
