Constraints to cull bright objects + cosmetic modifications:
Constraints to cull bright objects + cosmetic modifications:

- Script modified to cull bright stars through constraints gmag > 11
- Script modified to cull bright galaxies throught constraint g_ab > 11
- tested to work with e203093613e30f1939ed40a9fad7ff46674c9ab7 of
  sims_catUtils/newTwinklesCatalog]examples
- With boundLen 0.03 this takes of the order of 40 sec with the g_ab >
  11 constraint taken out. With this constraint it takes about 23 mins,
but this could reflect users on the database
