Read Stan samples from a CSV file. Columns that belong to the same variable are grouped into arrays.

```julia

julia> using StanSamples

julia> DATA = "a,b.1,b.2,c.1.1,c.2.1,c.1.2,c.2.2\n" *

              "1.0,2.0,3.0,4.0,5.0,6.0,7.0\n" *

              "8.0,9.0,10.0,11.0,12.0,13.0,14.0"

julia> samples = read_samples(IOBuffer(DATA));

julia> samples.a

2-element Array{Float64,1}:

julia> samples.b
