// DESCRIPTION:
// client side entity commands

/*
The cg_command system is used for a variety of different functions, but mostly it is 
used for spawning client side temp models.  Either through the use of emitters or
commands that are tied to various frames of animation.

The ctempmodel_t class is the data structure for all of the static tempmodels.  
These are updated every frame and refEntity and refSprite data is created and added
to the renderer for drawing.

The spawnthing_t is the intermediate data holder.  When the TIKI file is processed
the spawnthing_t is cleared out and values are assigned based on the commands issued.

cg_common_data is a list of common data elements that are the same in the ctempmodel_t and
the spawhthing_t

After the m_spawnthing is filled in, 1 or more ctempmodel_t structures are spawned.

The ClientCommandManager is the listener that process all of the commands in the 
TIKI file, similar to ScriptMaster in the server game dll.
