eltype for some iterators is incorrect

[tkoolen]

vr = SimpleVRepresentation([1 2; 3 4])

for p in points(vr)
    println(typeof(p))
end

prints (as expected):

Array{Int64,1}
Array{Int64,1}

However,

eltype(points(vr))

is Int64.

This causes issues with collect(points(vr)), for example.

Same for rays, possibly others.

Thanks for the great library by the way!

Thanks for the feedback. This should be fixed in #11 CDDLib needs to be updated too since it used eltype on iterators as a feature, this if fixed in JuliaPolyhedra/CDDLib.jl#8, I will wait before Polyhedra is tagged before merging it but you can checkout to the branch eltypeit if you do not want to wait :) Polyhedra's new tag won't happen before #6 is fixed.
