trapz fails on vector integrands

[mzaffalon]

vx=range(0,1,length=10)
vy=range(0,2,length=20)
vz=range(0,1,length=30)
M=[[x, x^2+y^2+z^2] for x=vx,y=vy,z=vz];
trapz((vx,vy,vz),M) #-> ERROR: MethodError: no method matching one(::Type{Vector{Float64}})

but the signature for https://github.com/francescoalemanno/Trapz.jl/blob/master/src/kernels.jl#L19 is M <: AbstractArray{Tm,Nm}. Can Trapz.jl be extended to vector integrands?

just use

[trapz((vx,vy,vz),getindex.(M,i)) for i = 1:2]
