Assigns a datatable to use for the Chart.

Sets any configuration option, with no checks for type / validity

This is method was added in 2.5 as a bandaid to remove the handcuffs from users who want to add options that Google has added, that I have not. I didn't intend to restrict the user to only select options, as the goal was to type check and validate. This method can be used to set any option, just pass in arrays with key value pairs for any setting.

If the setting is an object, per the google docs, then use multi-dimensional arrays and they will be converted upon rendering.
