function FBCModel = FBCModel_create(varargin)
% FBCModel = FBCModel_create(level, version, pkgVersion)
%
% Takes
%
% 1. level, an integer representing an SBML level
% 2. version, an integer representing an SBML version
% 3. pkgVersion, an integer representing an SBML package version
%
% Returns
%
% 1. a MATLAB_SBML FBC FBCModel structure of the appropriate level, version and pkgVersion
