Linking AC and Bolt variables

This script allows Global Variables made with AC to be linked with Application and Saved variables made with Bolt.

To use it: The variables will now be linked - so changing its value in one asset will update the value of its associated variable in the other.
 * 1) Create a new Global Variable in AC's Variables Manager, and set it's Link to field to Custom Script.
 * 2) Create a new Application or Saved variable in Bolt's Variables window, and have it match the type made in AC (Float, Boolean, etc)
 * 3) Paste the code below into a C# script named BoltVariableLink.cs, and attach it to a GameObject in the scene
 * 4) In the component's Inspector, increase the Size field by 1, and fill in the fields that appear.  The AC Variable ID is the number that appears beside a variable's name in the Variables Manager
