object Catalyst

This class provides a compatibility layer for Spark Catalyst. It is used to createnew Expressions using constructors compatible with the runtime version of Spark Catalyst. This is necessary to address running Pathling in Databricks environments, which habitually use different (newer) version of Catalyst that one used by the corresponding Spark public release.
