 * Build the most common type of input processor, which can handle data from stdin, a specified

 *   1. file
 *   2. stdin
 *   3. alternateInputProcessors in the order they are listed
 *
 * @param alternateInputProcessors User input processors. Most commonly this will be a single
 * input processor that asks the user questions and builds input data based on their responses.
 * Another less common use case (which might co-exist with a Q&A input processor) would be building
 * the data from command line options.
