/* Purpose: Provides routines necessary for converting the */
/* the LHS of a rule into an appropriate form suitable for */
/* the KB Rete topology. This includes transforming the */
/* LHS so there is at most one "or" CE (and this is the */
/* first CE of the LHS if it is used), adding initial */
/* patterns to the LHS (if no LHS is specified or a "test" */
/* or "not" CE is the first pattern within an "and" CE), */
/* removing redundant CEs, and determining appropriate */
/* information on nesting for implementing joins from the */
/* right. */
