Caveats

• DO NOT add data in your topic (like foo/bar/item_123) instead add it in your data. Because every new topic would occupy some extra memory and would slow down the matching algorithm.
• Please note that pubEvents and subEvents are sanitized before getting into the system, i.e. empty parts are removed (/foo//bar/baz/ => foo/bar/baz), hence pubEvent & subEvents in the context (ctx) would contain the sanitized-events and not the original event.
• *** or ***... is considered as a normal string and not as a pattern!!
• Order of subscription is not the order of execution for pattern subscribers
• CANNOT use patterns for publishing. If used then, it'll be treated as normal strings
