small change to new example

examples/remove_add_components.py

-# Example showing how to remove and add components with Pykat.
-# Commands that get parsed into a pykat object can be interacted 
-# with in a object orientated manner. So you can call kat.component.remove()
-# to remove it for example.
-#
-# This example shows how a kat object can be manipulated when pykat objects
-# are available.
-#
-# If the a Finesse command hasn't been implemented as a pykat object yet
-# the command will be added as an "extra line", these can still be removed
-# and added to using the kat.removeLine and kat.addLine commands.
