DasePad/tests/container/loadSettings.js

/*
 * ACHTUNG: this file is a hack used to load "settings.json.docker" instead of
 *          "settings.json", since in its present form the Settings module does
 *          not allow it.
 *          This is a remnant of an analogous file that was placed in
 *          <basedir>/tests/backend/loadSettings.js
 *
 * TODO: modify the Settings module:
 *       1) no side effects on module load
 *       2) write a factory method that loads a configuration file (taking the
 *          file name from the command line, a function argument, or falling
 *          back to a default)
