%       vmcmesh = importToastMesh(toastmesh)
%
% EXAMPLE:
%cd
%       rad = 25;
%       nsect = 6;
%       nring = 32;
%       nbnd = 2;
%       [vtx,idx,eltp] = mkcircle(rad,nsect,nring,nbnd);
%       toastmesh = toastMesh(vtx,idx,eltp);
%       vmcmesh = importToastMesh(toastmesh);
%
% DESCRIPTION:
%
%       This is a wrapper function that converts the data in
%       an instance of the toastMesh class into the mesh structure
%       of ValoMC.
%
% INPUT:
%
%       toastmesh   - toastMesh class
%
% OUTPUT:
%
%       vmcmesh     - vmcmesh structure
