/***************************************************************************************
 *
 *  Example 7: Send any type of token.
 *
 *  Instructions:
 *      (1) - Select Network and Address by commenting/uncommenting the desired
 *              NETWORK section and providing valid BCH address.
 *
 *      (2) - Select a Validation method by commenting/uncommenting the desired
 *              VALIDATOR section. Chose from remote validator or local validator.
 *              Both options rely on remote JSON RPC calls to rest.bitcoin.com.
 *                  - Option 1: REMOTE VALIDATION (rest.bitcoin.com/v2/slp/isTxidValid/)
 *                  - Option 2: LOCAL VALIDATOR / REST JSON RPC
 *                  - Option 3: LOCAL VALIDATOR / LOCAL FULL NODE
 *
 *      (3) - Run `tsc && node <file-name.js>` just before script execution, or for
 *              debugger just run `tsc` in the console and then use vscode debugger 
 *              with "Launch Current File" mode.
