# modified to work in SU6 using observer classes
# Usage : adds 'Start Recording' 'Stop Recording' to plugins menu
#          Select the start recording, then go about modeling as usual. SU will
#          record a jpg image everytime the view is refreshed, ie. whenever an entity added
#          or simply orbit,pan operation is done. You can collect the numbered images and make movie 
#          using 'windows movie maker'.
#
# limitations : Target folder is hard coded.
