Browse Source 
- [CHG] Reorganitzacions i neteja de codi
- [NEW] Constants del espai io en la seua pròpia capçalera
- [NEW] Comentaris en algunes parts menys obvies del codi
- [CHG] Alguns defines passats a constexpr
- [CHG] display::init() no feia més que cridar a display::reinit(). Concretats els dos en display::init()
