% author: Qianqian Fang (q.fang <at> neu.edu)
%
% input:
% inputfile: the output file name to the JMesh
% *.bmsh for binary JMesh file
% *.jmsh for text JMesh file
% options: (optional) if loading from a .bmsh file, please see the options for
% loadbj.m (part of JSONLab); if loading from a .jmsh, please see the
% supported options for loadjson.m (part of JSONLab).
%
% output:
% jmsh: a structure (array) or cell (array). The data structure can
% be completely generic or auxilary data without any JMesh
% constructs. However, if a JMesh object is included, it shall
% contain the constructs defined in the JMesh specification
%
% example:
% [no,fc,el]=meshasphere([0 0 0],50,3,10);
% savejmesh(no,fc,el,'box.jmsh');
% newmesh=loadjmesh('box.jmsh');
