function h=GetMaxLengthEdges(q,me)
% function h=GetMaxLengthEdges(q,me)
%   Computation of the maximal value of edge lengths
%   
% Parameters:
%  q: Array of vertices coordinates, `2\times\nq` array. <br/>
%  `{\q}(\il,j)` is the
%  `\il`-th coordinate of the `j`-th vertex, `\il\in\{1,2\}` and
%  `j\in\ENS{1}{\nq}`
%  me: Connectivity array, `3\times\nme` array ('int32'). <br/>
%  `\me(\jl,k)` is the storage index of the
%  `\jl`-th  vertex of the `k`-th triangle in the array `\q` of vertices coordinates, `\jl\in\{1,2,3\}` and
%       `k\in{\ENS{1}{\nme}}`.
% 
% Return values:
%  h: maximal length of an edge in the mesh
