[Android Viewer] Add header funcs to Calc

Added insert/delete/hide/show/optimal width or height
/adjust width or heigth  to Calc. These options
show in a floating menu near the headers when the
user taps on the headers. Also added selection on
headers, i.e., user can drag on headers to select
multiple columns/rows.
