I had implemented a few shift arrays operations in some of my packages which I would be glad to port to use `ShiftedArrays` instead. As for the time series, I did work at a neuroeconometrics lab for a few years so I am familiar with those operations. Might be nice to provide a function to resample and provide statistic by various intervals. For example, a `Vector{<:DateTime}` that can resample the mean from `seconds` to `minutes` and whatnot.
