// Description...: Generates decision rules.
//
// Comments......: Assumes that library clients use handles.
//
//                 Excerpt from the RSES technical doc.:
//
//                   Generates decision rules for all reducts of
//                   type 0 (not related to objects) from rr_mem
//                   on the basis of decision table table.
//
//                   Note: Decision rules for object related reducts
//                   (type 1) are calculated automatically when
//                   calculating reducts.  If rr_mem contains
//                   object related reducts then those reducts are
//                   omitted by GenerateRules().
//
//                   Remark: Decision rules of both types could be
//                   computed automatically when calculating reducts
//                   but in case of not object related reducts number
//                   of rules may be huge.  Thus the separate function
//                   GenerateRules is implemented.
