This package utilizes AxisIndices to interface with data that has a time axis.

```julia

julia> using TimeAxes, Dates

julia> t = TimeAxis(Second(1):Second(1):Second(10))

TimeAxis(1 second:1 second:10 seconds => Base.OneTo(10))

julia> t2 = t[Second(1)..Second(3)]  # index by time interval

TimeAxis(1 second:1 second:3 seconds => 1:3)

julia> t[:ts1] = Second(1);

julia> t[:ts2] = Second(3);

julia> t2 = t[:ts1..:ts2]  # index by interval between two time stamps

TimeAxis(1 second:1 second:3 seconds => 1:3)

julia> t[>(:ts2)] == t[>(Second(3))]  # all time points above :ts2 and 3 seconds returns the same thing

true

julia> x = AxisArray(ones(10, 2), t)

10×2 AxisArray{Float64,2}

 • dim_1 - 1 second:1 second:10 seconds

 • dim_2 - 1:2

                 1     2

    1 second   1.0   1.0

   2 seconds   1.0   1.0

   3 seconds   1.0   1.0

   4 seconds   1.0   1.0

   5 seconds   1.0   1.0

   6 seconds   1.0   1.0

   7 seconds   1.0   1.0

   8 seconds   1.0   1.0

   9 seconds   1.0   1.0

  10 seconds   1.0   1.0

julia> x[:ts1..:ts2,:]

3×2 AxisArray{Float64,2}

 • dim_1 - 1 second:1 second:3 seconds

 • dim_2 - 1:2

                1     2
