NAME
process_input - provide a hook for the MudOS driver to send a copy of what the
player is typing to the player object.
SYNOPSIS
string process_input(string)
DESCRIPTION
If process_input is present in the player object, then the MudOS driver
parser will send it a copy of each line the player types. Process_input
makes it easy to implement features like command history and protection
against wizcuffs. process_input can also modify the player input before it
is parsed. If process_input returns a non-zero string, that string is
used by the driver instead of what the player typed.
