v3.1.0 (Swift 4.1)

Changes

• By default, the return key is used to create a tag in the field. Now, you can change it and use the comma or the space key instead: tagsField.acceptTagOption = .space.
• onDidEndEditing and onDidBeginEditing events were removed in favor of UITextFieldDelegate methods (textFieldDidBeginEditing(textField:) and textFieldDidEndEditing(textField:)). The delegate should be assigned to the textDelegate property and it's related with the input text field. It's also a nice way to have access to textFieldShouldReturn(textField:) where it's possible to change the first responder when the return key is free (i.e.: tagsField.acceptTagOption = .comma is set).
