Help Text

MAKE_DEFAULT_STUDY - Create simulated default data and link to a simulated subject
 function make_default_study(STUDY,SUBJECT);
 
 Invokes the simulator and stores a simulated data set in the STUDY folder,
  linked to an assumed default data set in the SUBJECT folder.
 STUDY and SUBJECT should be referential to the current database
