function CSX = AddPolyhedron(CSX, propName, prio, vertices, faces, varargin)
% CSX = AddPolyhedron(CSX, propName, prio, vertices, faces, varargin)
%
% Add a polyhedron to CSX and assign to a property with name <propName>.
%
% prio: primitive priority
% vertices: cell array of all vertices
% faces: cell array of all faces
%
% Note: - The polyhedron must be a closed surface for 3D discretisation
% - All faces must contain the vertices in a right-handed order with
% the normal direction for each face pointing out of the solid
%
% optional:
% Transformation: perform a transformation on a primitive by adding
% e.g.: 'Transform', {'Scale','1,1,2','Rotate_X',pi/4,'Translate','0,0,100'}
% Note: This will only affect the 3D material/metal discretisation
%
% example:
% % example tetrahedron
% vertices{1}=[0 0 0];
% vertices{2}=[1 0 0];
% vertices{3}=[0 1 0];
% vertices{4}=[0 0 1];
% faces{1}=[0 2 1];
% faces{2}=[0 1 3];
% faces{3}=[0 3 2];
% faces{4}=[1 2 3];
% CSX = AddMetal( CSX, 'metal' );
% CSX = AddPolyhedron(CSX, 'metal', 0, vertices, faces);
