 * Pattern-specific match representation of the hu.bme.mit.incquery.cep.runtime.evaluation.queries.guardAtomicPattern pattern, 
 * to be used in conjunction with {@link GuardAtomicPatternMatcher}.
 * 
 * <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.
