/**
 * Utility class providing additional operations on DirContexts.
 * Instead of extending DirContext we use a helper who will work
 * on any context, including 'foreign' ones ( like JNDI, etc ).
 *
 * Typical methods - conversions ( int, boolean), etc.
 *
 * This code should check if the context extend our BaseDirContext
 * and use specific features ( like notes - to cache the conversion
 * results for example ), but fallback for external contexts.
