The functions defined in the DataSource class must be implemented in the custom data source for each
new data set, taking steps to convert data and normalize data access. It is good practice to ensure that
custom data sources "extend" DataSource by using the DataSource()
constructor as the line that creates the
custom DataSource S3 objects, and then overriding functions as required.
