### Multi-dimensional Arrays

julia> ma = [[1,2] [3, 4]]
2×2 Array{Int64,2}:
 1  3
 2  4

julia> ma == hcat([1,2], [3,4]) == [1 3; 2 4]
true

julia> ndims(ma)
2

julia> size(ma)
(2, 2)

julia> eltype(ma)
Int64

julia> ma[1]
1

julia> ma[:,1]
2-element Array{Int64,1}:
 1
 2

julia> ma[:,1][2]
2

julia> ma[1,1]
1

julia> ma[2,1]
2

julia> ma[1,2]
3

julia> ma[2,2]
4


### Nested Array

2-element Array{Array{Int64,1},1}:
 [1, 2]
 [3, 4]

julia> ndims(na)
1

julia> size(na)
(2,)

julia> eltype(na)
Array{Int64,1}

julia> na[1]
2-element Array{Int64,1}:

julia> na[1][2]
2

julia> na[1][1]
1

julia> na[1][2]
