NSTableView automatically adjust height to fit cell view

Reference: Using auto-layout to calculate table cell height In ‘Using auto-layout to calculate table cell height’, it’s introduced how to use auto-layout to update table view’s (UITableView) cell height with Objective-C language.

Remember one thing post ‘Using auto-layout to calculate table cell height’ has warned that this method is not that efficient, figure out the way make it more efficient yourself.

Make text table view(NSTableView) auto resize

To make a iMessage-like chat table view, there is several steps to follow: Text field should be able to adjust its size automatically.
