// CreateHITRequest returns a request value for making API operation for
// Amazon Mechanical Turk.
//
// The CreateHIT operation creates a new Human Intelligence Task (HIT). The
// new HIT is made available for Workers to find and accept on the Amazon Mechanical
// Turk website.
//
// This operation allows you to specify a new HIT by passing in values for the
// properties of the HIT, such as its title, reward amount and number of assignments.
// When you pass these values to CreateHIT, a new HIT is created for you, with
// a new HITTypeID. The HITTypeID can be used to create additional HITs in the
// future without needing to specify common parameters such as the title, description
// and reward amount each time.
//
// An alternative way to create HITs is to first generate a HITTypeID using
// the CreateHITType operation and then call the CreateHITWithHITType operation.
// This is the recommended best practice for Requesters who are creating large
// numbers of HITs.
//
// CreateHIT also supports several ways to provide question data: by providing
// a value for the Question parameter that fully specifies the contents of the
// HIT, or by providing a HitLayoutId and associated HitLayoutParameters.
//
// If a HIT is created with 10 or more maximum assignments, there is an additional
// fee. For more information, see Amazon Mechanical Turk Pricing (https://requester.mturk.com/pricing).
//
//    // Example sending a request using CreateHITRequest.

//    resp, err := req.Send(context.TODO())
//    if err == nil {
