Add Xamarin.iOS Support

Add Xamarin.iOS Support        
        * Added Xamarin.iOS Binding
        * Added Xamarin.iOS Sample app
        * Added creation of Xamarin Component for the Component Store

Special Notes:
        Inside Xamarin folder there is a makefile that handles everything for you
	make: Will compile TaplyticsSDK.csproj and create TaplyticsSDK.dll
	make component: Will create TaplyticsSDK.dll, download xamarin-component.exe and create the .xam file that is the one you upload to Xamarin Component Store
