Advanced Trains [advtrains] API documentation
--------
To use the API, mods must depend on 'advtrains'.
All boolean values in definition tables default to 'false' and can be omitted.
### Wagons
Wagons are registered using the function

advtrains.register_wagon(name, prototype, description, inventory_image)
- 'name' is the internal name of the wagon. It should follow the mod naming convention, however, this is not enforced.
	For compatibility reasons, if a mod name is omitted, the wagon will be registered in the advtrains: namespace.
	Example: A wagon with name="engine_tgv" will be registered as "advtrains:engine_tgv".
	!IMPORTANT! You must not append a ":" at the start of the name, even if you want to bypass the mod naming convention check. This is because internally the register_wagon function
	appends a ":" automatically.
- 'prototype' is the lua entity prototype. The regular definition keys for luaentites apply. Additional required and optional properties see below. DO NOT define 'on_step', 'on_activate', 'on_punch', 'on_rightclick' and 'get_staticdata' since these will be overridden. Use 'custom_*' instead.
- 'description' is the description of the inventory item that is used to place the wagon.
- 'inventory_image' is the inventory image of said item.

# Wagon prototype properties
{
	... all regular luaentity properties (mesh, textures, collisionbox a.s.o)...
	drives_on = {default=true},
	^- used to define the tracktypes (see below) that wagon can drive on. The tracktype identifiers are given as keys, similar to privileges)
	max_speed = 10,
	^- optional, default 10: defines the maximum speed this wagon can drive. The maximum speed of a train is determined by the wagon with the lowest max_speed value.
	seats = {
	^- contains zero or more seat definitions. A seat is a place where a player can be attached when getting on a wagon.
		{
			name="Left front window",
			^- display name of this seat
			attach_offset={x=0, y=10, z=0},
			^- this value is passed to 'set_attach'
			view_offset={x=0, y=6, z=0},
			^- player:set_eye_offset is called with this parameter.
