/**
 * Defines a suite of plan node-specific methods for the computation of logical properties.
 * Supplies a default implementation that produces an empty set of logical properties, and additionally,
 * a suite of plan-node specific overrides of the default implementation. The implementations leverage
 * property propagation builders supplied by LogicalPropertiesImpl. The LogicalPropertiesProvider
 * mechanism enables a plan node to receive its logical property compute capabilities via dependency injection.
 * This is needed because the computation of logical properties requires analysis of plan node's argument expressions,
 * and the code the performs this analysis must be built in presto-main as this is where expression related classes are visible.
 * The property computation implementation is dynamically injected into the presto-spi and presto-main plan node method's responsible
 * for computing logical properties. This interface is defined in presto-spi where it is visible to all plan nodes. The
 * implementation LogicalPropertiesImpl is provided in presto-main as per the reasons described above.
