Typeahead should take datasets as an array (not just list)

[vitalpoltava]

Hello,

Sometimes (when I use the typeahead.js in a widget) I do not know how many datasets will go to init phase and I need to provide those datasets as an array. I tried to use typeahead.apply(context, datasests), but seems it is not applicable, as can't provide context (please let me know if there is a way). So, it would be nice to have an ability to provide multiple datasets, wrapped in array list, as a second argument. To achieve this I'd offer to add something like the following to the initialize method:

var datasets = _.map([].slice.call(arguments, 1), function(el) {return el;});

It will serve both situations (when we provide datasets as an array and as a list of arguments).

Regards!

Good thinking. This should be a pretty simple change, I'll aim to get it in the next release (v0.10.1).
