Alright, Borja, here's a more descriptive commit message. Fixed message decoder to correctly read the recv buffer over to a buffer that will become a message string. Deleted lots of useless tests. Still need to fix the handler function. Morale is relatively high. High of 20 with a cold front coming in tonight leading to a low of 3, the sky will be partially cloudy. Such descriptive, much project 1b. Wow.

Huge commit. [...] The weather tonight will be clear, with a 50% chance of showers tomorrow. , out.

Pthread implementation added into main function [...]. Cloudy skies into the late afternoon with a chance of showers after midnight. Morale is high, but you have died of dysentery.
