Adds DependentBootstrap as a dependency to Bootstrap, and wraps the block bootstrapping methods in DependentBootstrap with new sampling methods StationarySampling, MovingBlockSampling, CircularBlockSampling, and NoOverlapBlockSampling. Relevant issue #45

Thank you, this looks very nice! It might take some time to test and review the changes - I'll try to finish it as soon as I can.

No worries, take your time. I certainly did :-) (sorry about that BTW, I had a few unexpected work things come up)

Hey Folks, I was wondering what the latest was on this PR? I was hoping to use some Dependent bootstrapping for time series analysis.

[colintbowers]

Not sure, I haven't heard anything. However, I can say with certainty that the test suite I added as part of this PR will fail on the latest Julia version since the internals of rand have changed. I've been meaning to try and come up with a test procedure that doesn't depend on random number generation for a while now but haven't found the time.
