Allow %memit to return a result object and to be quiet

[wasade]

An example of its use is below. The object and implementation were adapted from IPython's timeit returnable.

> %load_ext memory_profiler

> %memit -r 10 1+2
peak memory: 25.06 MiB, increment: 0.15 MiB

> result = %memit -o -r 10 1+2
peak memory: 24.10 MiB, increment: 0.01 MiB

> result
Out[4]: <MemitResult : peak memory: 24.10 MiB, increment: 0.01 MiB>

> result.mem_usage
Out[5]:
[24.0859375,
 24.09765625,
 24.09765625,
 24.09765625,
 24.09765625,
 24.09765625,
 24.09765625,
 24.09765625,
 24.09765625,
 24.09765625]

This seems to duplicate _repr_pretty_ of MemitResult.

[wasade]

Close, but not exactly, as the logic of _repr_pretty_ writes to a RepresentationPrinter supplied by IPython. I've refactored though so a __str__ can be obtained from MemitResult and revised the if-statement in memit.

Thanks for the patch. Could you take into account @superbobry's comments? Otherwise the code looks good to me.

Merged. Thanks @wasade for the patch and @superbobry for the comments

[wasade]

Great, thank you both!
