Is your feature request related to a problem? Please describe.
I've had several occasions when I wanted to retype the TOTP secret (not the code, but the secret key) from the edit dialog. For instance when transferring to a device which doesn't have a camera for the QR code. In all of those occasions I had issues recognizing 0s from Os.

Describe the solution you'd like
In the edit dial

Expected Behavior

Find examples and instructions for the NCCO builder with this repo.

Current Behavior

No formal documentation, but some examples exist in the code snippets.

Possible Solution

Add a new section to the README to cover

Expected Behavior

We want to allow for a full url or domain to be used in a apiHost or restHost option.

const vonage = new Vonage({
  apiKey: VONAGE_API_KEY,
  apiSecret: VONAGE_API_SECRET
  apiHost:'myurl.com'
})

const vonage = new Vonage({
  apiKey: VONAGE_API_KEY,
  apiSecret: VONAGE_API_SECR
