ADAM / AIAHTML5

also the alignment of scrollbar issue is fixed in list manager.

The case where user first clcik on normal mode then extract then again highlight then we need to call highlight body in gray mode
and then highlight the previously selected body regions at the time of normal mode.

Implemented extract.

2. few modifications in DA controller

null checks in draw image

…hat new worker process can get space.

…orker. sending back the updated gray canvas data for a single region.
This works well for cases except we click multiple time at very less interval. Need to destroy previous worker process on every click.

…or on two body regions

…ons and in each iteration a new worker process is initialize i.e secon worekr process in which looping is done on term list for a single body regiona nd it returns the updated grayimagedata along with BRID, we hold this returned data in first worker process in an array whch is indexed by bodyregion. and once all process for all bodyregions are comlpeted then we return this indexed array to the controller and loop through thsi aaray and put updated data on respective canavs

…all termlist together for single body region return the updated data back to html to put on canavs.

… it is coloring the last one because the grayimage data is the initial one and on second iteration the worker process is having initial gary data so we need to send updated gray data for each iteration of term number
