Identify User
This function should be called on page load with a set of user properties that you want to personalize by.
Example:
frase.identify({ "email" : "john@email.com" ' });
You can call this function multiple times per page to build up the properties on the user object if you're loading data asynchronously. For example:
YourAPI.getUsers(function(data) { frase.identify({ "email" : data.email }); });
