we will use this port in net.h
#define PORT 36911

here packet size is also defined, subject to change but makes it 
easy to no block on send
#define PACKSZ 1024


pack type will be at the front of the packet to ensure we handle packets right

enum pack_type{
  G_STATE, S_STATE, HOSTS_REQ, NEW_HOST, JOIN_REQ, U_NAME    
};

packets are defined so that they keep the exact size of PACKSZ
typedef struct packet{
  enum pack_type type;
  char payload[PACKSZ - sizeof(enum pack_type)];
} packet;
