Fixed #6, added relevant test code
Pep8 compliance changes
Set up the QueryManager in a metaclass instead of in the __new__ method, which means one doesn't have to instantiate an instance of the class before querying it. Fixed the __iter__ method of Queryset, which yielded only the first object from the query. Put back test cases for CloudCode functions.
Fixed merge conflicts- new version as per #8 should be ready.
Brought README.mkd up to date with new version (pull request #8). Also removed >>> in each of the example Python code snippets- they end up being confusing since they make it harder to cut-and-paste code. Incremented version.
Made Queryset Consistent, Moved user.py into __init__

Many changes:

- Removed the QueryManager class- all querying is now handled by the
Queryset class. This was necessary to manage chained query lines like

GameScore.Query.gte("score", 1000).lt("score",
2000).order("playerName")

- Queryset methods for comparison and options are now added
programatically (makes it easier to change their operation all at
once).

- Added test coverage of querying methods, including comparison
operators and limit/skip options.

- Removed user.py, moving its classes into `__init__.py`. The reason is
that lines like

import parse_rest
from parse_rest.user import User

parse_rest.APPLICATION_ID = "something"

meant the module attribute APPLICATION_ID was actually not accessible
from the User class. Perhaps there's a way to make this work- I just
couldn't find it yet.

- Set up createdAt and updatedAt to return date time objects rather
than strings
Fixed #9- can save Pointers to Objects

Fixed #9 by allowing ParseResources to be converted into Pointers and
back, such as when one object is set as an attribute of another. This
required:

- ParseResource now inherits Pointer
- All values are now converted to ParseType in the initialization of a
ParseResource
- The `_to_native` method of ParseResource was changed to `_to_dict`,
which allows `_to_native()` to construct a Pointer when one object is
an attribute of another.

Also:

- Added test coverage and example to README

- Fixed bug where many `from_native` methods used `self` instead of
`cls`

- `class_name` is converted to a string before being assigned to
`DerivedClass.__name__` (necessary because it is unicode when returned
from Parse)

- Changed TestUser to rely on parse_user.User instead of
parse_user.user.User
