    /loncom/interface	loncreatecourse.pm 
  Log:
  Bug 263.  
  Changed oh-so descriptive function names of 'phase_one' and 'phase_two' to 
  'print_course_creation_page' and 'create_course'.
  Rewrote html for course creation page.  Now user must specify a home server 
  for a course.  Suggestions on determining a default server would be appreciated.
  When creating a course, now deal with course_home form parameter and pass it
  to lonnet.
