##check if ghostmode installed
- GhostMode ~= nil
- if it's not installed then GhostMode == nil
##meta functions ply:IsGhostMode() returns boolean isGhost ply:SetGhostMode( boolean ghost ) returns nil
##team TEAM_GHOST = 5
##issues
- does not seem to set players to TEAM_GHOST when they type the command
- solution - possibly add a conditional around the contents of the PlayerSpawn hook which checks ply:IsGhostMode() == true to avoid doing anything if the player is ghost - the addon will switch the player's team and THEN call the PlayerSpawn hook again, which means it will run normally since ply:IsGhostMode() will be false.
