I am just learning OOP and am writing this script and keep running into this problem.
To reproduce:

Run PUMASS_ObjLib.py
a = []
a.append(Schedule().Add())
a.append(Schedule().Add())
print a.AllDates[0]
print a.AllDates[1]

What happens is that when you add a new Date object, all other Date objects in the list turn into the one you just made.
Does any1 know how to fix this?
