/*
  Order Entity
  An Order Entity is nearly the same as an Offer. But while an Offer is generated
  by a webhook from P2WDB, the Order Entity is created internally. It is used
  to track an Order generated by this application.

  The Order tracks the hdIndex address used to hold tokens or BCH for sale.
