computeDataHash

Compute a hash of the data in the database schema. If the data changes, this
should produce a different hash code. Specifically, the hash is based on the
field names, field types, and table row counts.

An R 'DataBase Interface' ('DBI') compatible interface to various database platforms ('PostgreSQL', 'Oracle', 'Microsoft SQL Server',
'Amazon Redshift', 'Microsoft Parallel Database Warehouse', 'IBM Netezza', 'Apache Impala', 'Google BigQuery', 'Snowflake', 'Spark', and 'SQLite'). Also includes support for
fetching data as 'Andromeda' objects. Uses either 'Java Database Connectivity' ('JDBC') or other DB I drivers to connect to databases.
