Overview
The primary entry point into the extension system.
Registry holds the extensions which have been registered and activated, has methods for registering or defining a processor and looks up extensions stored in the registry during parsing.

#block(*args, &block) ⇒ Extension
Registers a BlockProcessor with the extension registry to process the block content (i.e., delimited block or paragraph) in the AsciiDoc source annotated with the specified block name (i.e., style).
The BlockProcessor may be one of four types:
-
A BlockProcessor subclass
-
An instance of a BlockProcessor subclass
-
The String name of a BlockProcessor subclass
-
A method block (i.e., Proc) that conforms to the BlockProcessor contract
Unless the BlockProcessor is passed as the method block, it must be the first argument to this method. The second argument is the name (coersed to a Symbol) of the AsciiDoc block content (i.e., delimited block or paragraph) that this processor is registered to handle. If a block name is not passed as an argument, it gets read from the name property of the BlockProcessor instance. If a name still cannot be determined, an error is raised.
