Started playing around with database API

Added code that prints a more readable representation of Poll and Choice
instances.

from polls.models import Poll, Choice
from django.utils import timezone

list(vars(Poll))
list(vars(Choice))

Poll.objects.all()
Choice.objects.all()

Poll.__doc__
Choice.__doc__

poll = Poll(question="Which 3d software do you like?",
pub_date=timezone.now())

poll.save()

poll.id
poll.question
poll.pub_date

poll.question = "Which 3D Software do you like????"

poll.save()

Poll.objects.all()[0]
