function asy_export(filename::String,nV::Int,nB::Int,E::Array{Int,2}, xs::Array{Float64,1},ys::Array{Float64,1})

write asymptote code in filename corresponding to a graph with nV vertices, nB boundary vertices, E edges. The x,y node positions are in x,y

–––

function graphml_load(filename::String)

load a graphml file and returns:

E Edge set x,y node positions r,g,b red, green, blue node color (integers) nb number of boundary nodes

belonging to the boundary is indicated by an integer called "bdry" associated to each node. bdry==0 means the node is an interior node and bdry==1 means the node is a boundary node. The nodes are reordered so that all the boundary nodes come first.

function graphml_save(filename::String,nV::Int,nB::Int,E::Array{Int,2}, xs::Array{Float64,1},ys::Array{Float64,1})

function graphml_save(filename::String,nV::Int,nB::Int,em::BitArray{1}, xs::Array{Float64,1},ys::Array{Float64,1})

function graphml_save(filename::String,nV::Int,nB::Int, t::Union{Array{Int,2},BitArray{1}})

write a graphml representation of filename corresponding to a graph with nV vertices, nB boundary vertices, E edges. The x,y node positions are in xs,ys. If ommitted, positions are taken at random
