function nFaces = meshFaceNumber(varargin)
%MESHFACENUMBER Returns the number of faces in this mesh.
%
% NF = meshFaceNumber(V, F)
% NF = meshFaceNumber(V, E, F)
% NF = meshFaceNumber(MESH)
% Returns the number of faces in the given mesh. As the face array may be
% represented either as numeric array or as cell array of indices, this
% function is a convenient way to get the number of faces independanlty
% of the mesh representation.

% Example
% [v f] = createCube;
% meshFaceNumber(v, f)
% ans =
% 6
