 * <p>Class fields correspond to parameters of the pattern. Fields with value null are considered unassigned.
 * Each instance is a (possibly partial) substitution of pattern parameters, 
 * usable to represent a match of the pattern in the result of a query, 
 * or to specify the bound (fixed) input parameters when issuing a query.
