77 ** Here we define the tables that make up the circ matrix. Conceptually, this implements
78 ** the "sparse matrix" that everyone talks about, instead of using traditional rules logic.
79 ** Physically, we cut the matrix up into separate tables (almost 3rd normal form!) that handle
80 ** different portions of the matrix. This wil simplify creation of the UI (I hope), and help the
81 ** developers focus on specific parts of the matrix.
86 -- ****** Which ruleset and tests to use *******
88 -- * Most specific range for org_unit and grp wins.
90 -- * circ_modifier match takes precidence over marc_type match, if circ_modifier is set here
92 -- * marc_type is first checked against the circ_as_type from the copy, then the item type from the marc record
94 -- * If neither circ_modifier nor marc_type is set (both are NULLABLE) then the entry defines the default
