Options List
Plugin supports many arguments. But, all arguments are optional except for the "user" option to set your Google+ profile ID..
You can place options array in a HTML5 data attribute "data-button".
Also, you can place options in HTML comment so It would not break HTML validation of your page.

Options must be separated by a comma, but a trailing comma is fatal.
