Working environment setup in main_heatmapHao.html

I have put the files to include in above html and updated the lib
directory to use both bootstrap and multiselect. Note: if we gonna use
multiselect, we can not use the nav bar of bootstrap, we can use what I
did for project 2 later.
Job for Hao: I will continue to work on main_heatmap_hao.html for the
major viz part.
Job for Alberto: Continue to develop on cloud tag and multi-select
plugin, you can update the environment by looking at the lib referenced
in main_heatmapHao.html
