customising the analytics snippet to clean PII : remove userID from page path.js for standard page reporting

clean_userID.js

// Checks to see if the current user's userID is found in the URL, if it is, remove it.

var userID = ""; // (Note, this assume the user ID is stored in a variable called `userID`)
if (document.location.pathname.indexOf('user/' + userID) > -1) {
  var page = document.location.pathname.replace('user/' + userID, 'user');
  ga('send', 'pageview', page);
}
