/*

|
This script will travers the HD wallet and sweep funds and tokens back
|
|
into the root address (index 0). That root address needs to have funds
|
|
to pay for the transactions.
|
|
|
|
This version will traverse the HD index of the wallet until it reaches
|
|
the value in the nextAddress property. This ensures that all UTXOs
|
|
that could be used by the wallet have been swept.
