A context provides a stack of scopes (represented by dictionaries).
Template directives such as loops can push a new scope on the stack with
data that should only be available inside the loop. When the loop
terminates, that scope can get popped off the stack again.
>>> ctxt = Context(one='foo', other=1)
>>> ctxt.get('one')
'foo'
>>> ctxt.get('other')
1
>>> ctxt.push(dict(one='frost'))
>>> ctxt.get('one')
'frost'
>>> ctxt.get('other')
1
>>> ctxt.pop()
{'one': 'frost'}
>>> ctxt.get('one')
