PDX_BOOL step_CheckTF(long option, int stepModel, DDF_TF sourceTF, DDF_TF targetTF)

# Purpose

Check if source DDF_TF is equal to target DDF_TF

# Description

The source DDF_TF is checked against the target DDF_TF for equality. If not equal, the super types of the source DDF_TF are retrieved and scanned against the target DDF_TF. This process is recursively performed until a match is found or there are no more super types.
