NumPyPy Status Update

Hello everyone

As expected, nditer is a lot of work. I'm going to pause my work on it for now and focus on simpler and more important things, here is a list of what I implemented :

• Fixed a bug on 32 bit that made int32(123).dtype == dtype("int32") fail
• Fixed a bug on the pickling of array slices
• The external loop flag is implemented on the nditer class
• The c_index, f_index and multi_index flags are also implemented
• Add dtype("double") and dtype("str")
• C-style iteration is available for nditer

Cheers
