 * ## **What follows are config instructions for older versions**
 * These are the default options which can be overridden with the initialization call like so:
 * **Example 1:**
 * <pre>
 * mermaid.initialize({

 *   }
 * });
 * </pre>
 *
 * **Example 2:**
 * <pre>

 *     },
 *
 *     securityLevel:'loose',
