A node module to allow for volunteer computing, like BOINC.

    if(disconnect) {

  //Declare err variable in order to create the error later
  let err;
  //If the error name is found in our list of errors
  if(errorList[error.name] !== undefined) {
    err = new errorList[error.name]();
  }
  //Otherwise it's just an unknown generic Error
  else {

  }
  //Set the message and the stack trace to the original error
  err.message = error.message;
  err.stack = error.stack;
  //Return the error
  return err;
