Description
Is there an already implemented way to slice an AxisArray along an axis from a given point to the end, similar to how one can slice a normal Array with integers? For example:
B = AxisArray(randn(Float64, (10, 10)), Axis{:time}(Date(2018, 1, 1):Day(1):Date(2018, 1, 10)))
We can do this:
B[5:end, :]
I would like to do something like:
B[Date(2018, 1, 5):end, :]

Research direction
Start by reproducing the issue's AxisArray example with date-based slicing and compare it with the working integer slice. Trace the existing AxisArray indexing entry point and related tests, then consider the issue done when B[Date(2018, 1, 5):end, :] returns the expected final six dates without regressing integer slicing.
