setindex not implemented

[daviehh]

Right now, one may read from the partition via .x[...], but not write:

using RecursiveArrayTools
u0=ArrayPartition(rand(2,2),rand(3,3),rand(4,4))
u0.x[1]=rand(2,2)

ERROR: MethodError: no method matching setindex!(::Tuple{Array{Float64,2},Array{Float64,2},Array{Float64,2}}, ::Array{Float64,2}, ::Int64)

For in-place updates f(du, u,p,t), it would be useful to be able to do the the assignment to du via the .x[...] index rather than the normal linear index.

Sorry, just found out broadcasting u0.x[1] .= rand(2,2) works as intended. Maybe add this to documentation?

u0.x is a tuple, so you can only mutate u0.x[1] by in-place operations.

@YingboMa got it, thanks!
