A CarouselArray is an Array type that allows for infinite, repeat-indexing. The CarouselArray acts as a custom-indexing wrapper for the Base Array. When indexed above its length, a CarouselArray will return the count from the first element of the Array. For example, in the case of [1, 2, 3, 4, 5], indexing 6 will give us 1.
my_array = CarouselArray([1, 2, 3, 4, 5])
my_array[6] == 1
Indexing 7 would give us 2, and indexing 0 would give us 5. The arrays repeat their few indices to an infinite level. Creating a CarouselArray is as straightforward as creating a regular Vector in Julia. This package is pretty minimalist, and only includes the CarouselArray and its indexing functions. Though they are called arrays, they are more similar to vectors.
setindex!(ca::CarouselArray{<:Any}, v::Any, i::Int64)
and getindex(ca::CarouselArray{<:Any}, i::Int64)
