-- | The Haskell LaTeX library.
--   
--   As it is said: "LaTeX is a high-quality typesetting system". This
--   library provides a bridge between that system and Haskell (i.e. it is
--   a LaTeX DSL).
--   
--   Write LaTeX documents with all the advantages you already have in
--   Haskell (recursion, type system, high order functions, ...), create a
--   LaTeX backend for your own program, make analysis of LaTeX code
--   through its Abstract Syntax Tree (AST), find another way to
--   pretty-printing values, ...
--   
--   See the <tt>examples</tt> directory in the source distribution to look
--   some simple examples. It would be good to get you started. Download
--   the HaTeX User's Guide from
--   <a>https://github.com/downloads/Daniel-Diaz/HaTeX-Guide/HaTeX-Guide.pdf</a>.

-- | The class of monoids (types with an associative binary operation that
--   has an identity). Instances should satisfy the following laws:
--   
--   <ul>
--   <li><pre>mappend mempty x = x</pre></li>
--   <li><pre>mappend x mempty = x</pre></li>

--   The method names refer to the monoid of lists under concatenation, but
--   there are many other instances.
--   
--   Minimal complete definition: <a>mempty</a> and <a>mappend</a>.
--   
--   Some types can be viewed as a monoid in more than one way, e.g. both
--   addition and multiplication on numbers. In such cases we often define
--   <tt>newtype</tt>s and make those instances of <a>Monoid</a>, e.g.

--   
--   Another approach could be to have custom counters, label management or
