title: Convert PHP 7 Error object to Exception?
body: <p>Our years of PHP code has been heavily using Exception handling by converting traditional errors to Exceptions via set_error_handler() and set_exception_handler(). After migrating to PHP 7 for some of our servers errors like this started pumping out:</p>
  
  <pre><code>Uncaught TypeError: Argument 1 passed to DataStellar\General\Exception_Handler::getContext() must be an instance of Exception, instance of Error given
  </code></pre>
  
  <p>We can use \Throwable as type hint but most of our code bases are still on PHP 5 servers. </p>
  
  <p>Is there any way we can easily convert an Error object to an Exception object here?</p>
