/**
 * ----------------------------------------------------------------------
 * SubmitPost.js - Module to send the browser to a URL via POST.
 *
 * SYNOPSIS:
 *
 *  SubmitPost.submit( 'https://some.host/wherever', {
 *      foo => 123,
 *      bar => "abc",
 *      baz => [ 234, "qwe" ],
 *  } );
 *
 * The above has the same effect as setting “location.href” but sends a
 * POST instead of a GET. The given object’s contents are encoded as a
 * standard HTML form submission.
 * ----------------------------------------------------------------------
