JSON parsefile does weird things to types.

Line 54 in 52f95ed

graph_dict = JSON.parsefile(graph_file)

One might expect that we would want graph dict to be
Dict{Int, Vector{Int})
or
Dict{String, Vector{String}
but JSON will go to Dict(String, Vector{Any}) by default, and so user will have to convert this manually after for some consistency.

Possible solution

If we wanted integers we could add the line

graph_dict = Dict(eachrow([[parse(Int,x) for x in keys(graph_dict)] collect(values(graph_dict))])) 

likewise for strings, and adjust any conflicts in the get_upstream_basins function
