Initial changes to support per-workbook CheckCell state.
Moved state data into separate state object. Excel Workbook events manage which state object is active.
Rename button handler to something more intuitive.
Again revert VS2013 update that prevents Excel 2010 from using plugin.
Updated Analyze button handler to use WorkbookState Analyze and Flag calls.
rm unused normal cutoff
Make underlying LINQ type an array instead of a list.
Correctly set UI state after user is shown the cell-fix form.
Add constant to globally disable parser exceptions.
Initial pass at an address cache. Address lookup overhead is very high for workbooks that contain large numbers of formulas; see included performance profile.
