Hello,
 Is there a way to catch errors in webdriverjs when the driver instance
 is created?
 In the example:
 var driver = new webdriver.Builder().
     usingServer('http://localhost:4444/wd/hub').
     withCapabilities({
       'browserName': 'chrome',
       'version': '',
       'platform': 'ANY',
       'javascriptEnabled': true
     }).
     build();
 If there is something wrong with my server, or my desired capabilities
 are not supported it will just throw and exception.
 It would be nice if we can pass an error handler function to the build
 metod so we could do something about it or exit nicely.
 
Also if I have multiple commands like;
 
driver.click().then(null, errHandler);
 ....
 driver.something().then(null, errHandler);
 
Is there any way to add a default errHandler that applies for every
 command so you dont have to add it to every single command? Maybe in
 the builder  something like  withErrorHandler(errHandlerFunction)
 
Is there any better to do this?
 
Thanks!
