Tests if a value is iterator-like.

@param {*} value - value to test
@returns {boolean} boolean indicating whether value is iterator-like

@example
var it = {
    'next': function noop() {}
};
var bool = isIteratorLike( it );
// returns true

@example
var bool = isIteratorLike( {} );
// returns false

@example
var bool = isIteratorLike( null );
// returns false
