Update of the China-VO AstroCloud

As the cyber-infrastructure for Astronomical research from Chinese Virtual Observatory (China-VO) project, AstroCloud has achieved solid progress during the last year. The proposal management system and data access system were redesigned. Several new sub-systems were developed, including China-VO PaperData, AstroCloud Statics and Public channel. More data sets and application environments are integrated into the platform. LAMOST DR1, the largest astronomical spectrum archive, was released to the public using the platform. The latest progress will be introduced.
