%ITAMESH Summary of this class goes here
% Detailed explanation goes here
%ITAMESH Represents a mesh used in simulations like FEM/BEM
% A mesh consists of a list of nodes (see itaMeshNodes) which form
% shell and/or volume elements (see itaMeshElements). Additionally,
% the nodes can be grouped using itaMeshGroup.
%
% Supported element shapes are tetraheadron/triangle (tetra) and
% quadrilateral (quad) with linear or parabolic order.
% For more information see itaMeshElements.
