+-- NAME
+--      Fast HC Code Inteligencer - exactly how to craft your fast HC
+--      Module: Final, fast solver. 
+--
+-- DESCRIPTION
+--
+--      This script shows how to craft a fast solver for your problem
+--
+--      It is broken down into Generic and Pro blocks, the pro blocks you can
+--      and adapt if needed
+--
+--      The design-goal of the file is to closely match what will be in the fast C++
+--      solver, so you can start with a generic and incrementally craft and test out the pro features
+--      
+--      The file is not based on generic tutorial scripts. Rather, it is rather technical
+--      based on techniques that originally solved a very hard problem and for the
+--      first time ever before, trifical pose from points and tangents Fabbri, etal, CVPR'10.
+--      It is important to keep in mind that, while there are novelties in the -- associated m2 
+--      scripts of PLMP, this version of them is the definitive account
+--      of what matterscarefully for writing a fast C++ solver
+--    
+--      Run ex-start first once
+--
+-- LEGEND
+--      - Ex and Pro marked bellow mean Example (simple) and Pro (fast)
+--      - YOU shows where can you make it faster for your problem
+
+-- OTHERS
+--      - Think of this as a prompt precise enough for LLM to help generate a fast solver
+-- 
+-- TODO
+--      - update with PLMP versions of common, etc, making _sure_ it
+--        doesn't impact performance
+--
+-- AUTHORS 
+--      Ricardo Fabbri (C++ and M2) and Timothy Duff (M2)
