The two most important functions the framework provides are:

1. `pgml.train(project_name TEXT, objective TEXT, relation_name TEXT, y_column_name TEXT)`,

The first function trains a model, given a human-friendly project name, a `regression` or `classification` objective, a table or view name which contains the training and testing datasets,

and the name of the `y` column containing the target values. The second function predicts novel datapoints, given the project name for an exiting model trained with `pgml.train`,
