-These fields are used as a drop-in replacement for element fields. They
-support time and increments so field values can be time dependent, even
-when interpolating. By default the last values are used.
-
-Examples
-========
-
->>> fs = FieldSet()
->>> fs[:displacement] = Vector[[1.0]]
-
->>> fs[:displacement]
-1-element Array{Array{T,1},1}:
- [1.0]
-
->>> fs[1][1][:displacement]
-1-element Array{Array{T,1},1}:
- [1.0]
-
->>> fs[end][end]:displacement]
-1-element Array{Array{T,1},1}:
- [1.0]
-
->>> fs[1].time
-0.0
-
->>> fs[1][end].increment_number
-0
