Option for specifying a class to set on a jStepper'ed input field #22
Description
When checking if a field already has jStepper initialized it would make it easier if the plugin had a built-in way of tagging the field with a class when initializing.
This class can be used for both checking if it's initialized but also to apply custom styling to a jStepper'ed field.
Default should probably be the current way: No class is added. And then you'd have to explicitly set a class name to add if you want the plugin to do this.
