Base Table test modules

In addition to test modules listed in Core test modules, the following model (table) oriented modules demonstrate how applications should subclass and use the methods in place to do database works:

./tests/test_25_base_table_crud_methods_postgresql.py

./tests/test_26_base_table_crud_methods_mysql.py

./tests/test_30_base_table_exception_postgresql.py

./tests/test_31_base_table_exception_mysql.py

These test modules, together with fixtures defined in ./tests/conftest.py should illustrate how the classes in this core module should work together.
