Change tool mode

This tutorial only applies to Xamarin.iOS.

Changing tools in Xamarin.iOS is identical to changing tools in iOS. See tutorial here.

// change to free text tool
var newTool = mToolManager.ChangeTool(new Class(typeof(pdftron.PDF.Tools.FreeTextCreate)));
((pdftron.PDF.Tools.Tool)newTool).BackToPanToolAfterUse = true;
