Authentication Failure Callback
                                    
                                        
setAuthFailureCallback(callbackFunction): void
                                    - This function is provided as a way to register a callback to another function to handle token failures or expiration.
 
Example
The following initializes a new embed client for the target instance of Pyramid and sets the authentication failure callback to a separate function called "AuthFailure". If the token fails, AuthFailure will be called and can handle the process from there.
var client = new pyramidEmbedClient("https://analytics.pyramid.com"); client.setAuthFailureCallback(AuthFailure); function AuthFailure(){ //do something here }
