A nodejs bindings implementation for selenium 2.0/webdriver

/**
 *
 * Send a sequence of key strokes to an element (clears value before). You can also use
 * unicode characters like Left arrow or Back space. WebdriverIO will take care of
 * translating them into unicode characters. You’ll find all supported characters
 * [here](https://w3c.github.io/webdriver/webdriver-spec.html#dfn-character-types).
 * To do that, the value has to correspond to a key from the table.
 *
 * <example>
    :setValueAsync.js
    client
        .setValue('.input', 'test123')
        .getValue('.input').then(function(value) {
            assert(value === 'test123'); // true
        });

    :setValueSync.js
    it('should demonstrate the setValue command', function () {
        var input = browser.element('.input');
        input.setValue('test123')

        console.log(input.getValue()); // outputs: 'test123'
    });
 * </example>
 *
 * @alias browser.setValue
 * @param {String}         selector   Input element
 * @param {String|Number=} values     Input element
 * @uses protocol/elements, protocol/elementIdClear, protocol/elementIdValue
