 * Parser constructor.
 *
 * @param config {Object} The parser configuration
 *      - options {Array} Array of option specs. See the README for how to
 *        specify each option spec.
 *      - allowUnknown {Boolean} Default false. Whether to throw on unknown
 *        options. If false, then unknown args are included in the _args array.
 *      - interspersed {Boolean} Default true. Whether to allow interspersed
 *        arguments (non-options) and options. E.g.:
 *              node tool.js arg1 arg2 -v
 *        '-v' is after some args here. If `interspersed: false` then '-v'
 *        would not be parsed out. Note that regardless of `interspersed`
 *        the presence of '--' will stop option parsing, as all good
 *        option parsers should.

 * Licensed under AFL-2.1 OR BSD-3-Clause
To use the validator call the validate function with an instance object and an optional schema object.
If a schema is provided, it will be used to validate. If the instance object refers to a schema (self-validating),
that schema will be used to validate and the schema parameter is not necessary (if both exist,
both validations will occur).
The validate method will return an array of validation errors. If there are no errors, then an
empty list will be returned. A validation error will have two properties:
"property" which indicates which property had the error
"message" which indicates what the error was
