Running the Sample code

The sample code creates a ledger with tables and indexes, and inserts some documents into those tables, among other things. Each of the examples in this project can be run in the following way:

python create_ledger.py

The above example will build the CreateLedger class with the necessary dependencies and create a ledger named: vehicle-registration. You may run other examples after creating a ledger.
