Need to add an example similar to the webj quorum but for talking to a geth node

Need to rework the nethereum example to get last block instead of an account balance

Need to add example for connecting via:
https://github.com/ethers-io/ethers.js

Need to add an example for connecting via:
https://github.com/ethereum/web3.py

Need to make a nethereum websocket example

let nodeUrl = "wss://" + USER + ":" + PASS + "@" + WSS_ENDPOINT;

// let provider = new Web3.providers.WebsocketProvider(nodeUrl);
let web3 = new Web3(new Web3.providers.WebsocketProvider(nodeUrl))
// Now you can call web3 functions, so we'll just test the connection by getting the latest block in the chain.

web3.eth.getBlock("latest").then((latestBlock) => {
console.log("Latest Block Via Websocket Provider: ");
console.log(latestBlock);

}).catch((er)=>{
console.log("error",er)
})

This code snippet results in following error:-

http_outgoing.js:494
throw new TypeError('The header content contains invalid characters');

Same code snippet runs when i replace kaleido url with rinkeby websocket url of infura.

Please Help!!!

Once webj adds support for basic auth or allows access to the request headers, we'll need to add a Websocket example for java/webj
