move_manager 
Acts as a namespace for movement packet/type related procs
Exists to provide an in code implementation of movement looping Replaces things like walk() or walk_to(), among others
Because we're doing things in engine, we have a lot more control over how different operations are performed We also get more say in when things happen, so we can subject movements to the whims of the master controller Rather then using a fuck ton of cpu just moving mobs or meteors
The goal is to keep the loops themselves reasonably barebone, and implement more advanced behavior and control via the signals
This may be bypassed in cases where snowflakes are nessesary, or where performance is important. S not a hard and fast thing
Every atom can have a movement packet, which contains information and behavior about currently active loops, and queuing info Loops control how movement actually happens. So there's a "move in this direction" loop, a "move randomly" loop
You can find the logic for this control in this file
Specifics of how different loops operate can be found in the movement_types.dm file, alongside the add to loop helper procs that use them

Proc Details
add_to_loop
Adds a movable thing to a movement subsystem. Returns TRUE if it all worked, FALSE if it failed somehow
force_move
Used for force-move loops, similar to move_towards_legacy() but not quite the same
Returns TRUE if the loop sucessfully started, or FALSE if it failed
Arguments: moving - The atom we want to move chasing - The atom we want to move towards delay - How many deci-seconds to wait between fires. Defaults to the lowest value, 0.1 timeout - Time in deci-seconds until the moveloop self expires. Defaults to infinity subsystem - The movement subsystem to use. Defaults to SSmovement. Only one loop can exist for any one subsystem priority - Defines how different move loops override each other. Lower numbers beat higher numbers, equal defaults to what currently exists. Defaults to MOVEMENT_DEFAULT_PRIORITY flags - Set of bitflags that effect move loop behavior in some way. Check _DEFINES/movement.dm
force_move_dir
Like move(), but we don't care about collision at all
Returns TRUE if the loop sucessfully started, or FALSE if it failed
Arguments: moving - The atom we want to move direction - The direction we want to move in delay - How many deci-seconds to wait between fires. Defaults to the lowest value, 0.1 timeout - Time in deci-seconds until the moveloop self expires. Defaults to infinity subsystem - The movement subsystem to use. Defaults to SSmovement. Only one loop can exist for any one subsystem priority - Defines how different move loops override each other. Lower numbers beat higher numbers, equal defaults to what currently exists.

freeze
Assigns a target to a move loop that immediately freezes for a set duration of time.
Returns TRUE if the loop sucessfully started, or FALSE if it failed
Arguments: moving - The atom we want to move halted_turf - The turf we want to freeze on. This should typically be the loc of moving. delay - How many deci-seconds to wait between fires. Defaults to the lowest value, 0.1 timeout - Time in deci-seconds until the moveloop self expires. This should be considered extremely non-optional as it will completely stun out the movement loop forever if unset. subsystem - The movement subsystem to use. Defaults to SSmovement. Only one loop can exist for any one subsystem priority - Defines how different move loops override each other. Lower numbers beat higher numbers, equal defaults to what currently exists. Defaults to MOVEMENT_DEFAULT_PRIORITY flags - Set of bitflags that effect move loop behavior in some way. Check _DEFINES/movement.dm

This would be done because the first item is the starting tile, which can break things timeout - Time in deci-seconds until the moveloop self expires.
