function y = isValidFBC(varargin)
% [valid, message] = isValidFBC(SBMLStruct, level, version, pkgVersion)
%
% Takes
%
% 1. SBMLStruct, an SBML structure
% 2. level, an integer representing an SBML level
% 3. version, an integer representing an SBML version
% 4. pkgVersion, an integer representing the FBC package version
%
% Returns
%
% 1. valid =
% - 1, if the structure represents
% a MATLAB_SBML FBC structure of the appropriate
% level and version
% - 0, otherwise
% 2. a message explaining any failure
%
% *NOTE:* The fields present in a MATLAB_SBML structure of the appropriate
% level and version can be found using getFieldnames(typecode, level, version)
