Inconsistent documentation of units

[paloha]

Today a typo took some of my time.

The unit specified here is "Mb":

memory_profiler/mprof.py

Line 216 in a99a3c3

This file contains the process memory consumption, in Mb (one value per line).""")

While the unit specified here is "MiB":

memory_profiler/memory_profiler.py

Line 327 in a99a3c3

memory usage, in MiB. It's length is always < timeout / interval

These are obviously not the same units and I believe the typo is in the file mprof.py and the unit should be corrected to "MiB" in both places. It is a small typo, but a since this is a memory profiler, I think it can cause a lot of headache to somebody.

That's not actually that small a typo. If it were "MB" instead of "MiB", that's one thing, but "Mb" is mega-bits which is a LOT different. (Though, I doubt anyone would really believe that memory consumption would be measured in megabits, because that makes no sense at all.)
