Public Class methods

new(position, options = {})

The points argument can be either a GLatLng object or an array of 2 floats. The options keys can be: :icon, :clickable, :title, :info_window and :info_window_tabs, as well as :max_width. The value of the info_window key is a string of HTML code that will be displayed when the markers is clicked on. The value of the info_window_tabs key is an array of GInfoWindowTab objects or a hash directly, in which case it will be transformed to an array of GInfoWindowTabs, with the keys as the tab headers and the values as the content.
