/**
 * 
 * A specialized parameter class for configuring {@code PropertiesConfiguration}
 * instances.
 * 
 * 
 * This class allows setting of some properties specific to properties
 * configuration, e.g. the layout object. By inheriting from
 * {@link FileBasedBuilderParametersImpl}, basic properties and properties
 * related to file-based configurations are available, too.
 * 
 * 
 * This class is not thread-safe. It is intended that an instance is constructed
 * and initialized by a single thread during configuration of a
 * {@code ConfigurationBuilder}.
