Description: The livelex Python module
        =========================
        
        This module is designed to parse text using rules, which are regular-expression 
        based. Rules are grouped into lexicons, and lexicons are grouped into a 
        Language object. Every lexicon has its own set of rules that describe the text 
        that is expected in that context.
        
        A rule consists of three parts: a pattern, an action and a target.
        
        * The pattern is a either a regular expression string, or an object that 
          inherits Pattern. In that case its build() method is called to get the 
          pattern.
        
        * The action can be any object, and is streamed together with the matched part 
          of the text. It can be seen as a token. If the action is an instance of 
          Action, its filter_actions() method is called, which can yield zero or more 
          tokens.  The special `skip` action skips the matching text.
        
        * The target is a list of objects, which can be integer numbers or references
          to a different lexicon. A positive number pushes the same lexicon on the 
          stack, while a negative number pops the current lexicon(s) off the stack, so 
          that lexing the text continues with a previous lexicon. It is also possible 
          to pop a lexicon and push a different one.
        
        Using a special rule, a lexicon may specify a default action, which is 
        streamed with text that is not recognized by any other rule in the lexicon.
        A lexicon may also specify a default target, which is chosen when no rule
        matches the current text.
