Description
A chain shape is a free form sequence of line segments. The chain has two-sided collision, so you can use inside
and outside collision. Therefore, you may use any winding order. Connectivity information is used to create smooth collisions.

Examples
Create world bounds using ChainShape
local body = world:createBody{type = b2.STATIC_BODY}
body:setPosition(0, 0)
local chain = b2.ChainShape.new()
chain:createLoop(
0,0,
application:getContentWidth(), 0,
application:getContentWidth(), application:getContentHeight(),
0, application:getContentHeight()
)
local fixture = body:createFixture{shape = chain, density = 1.0,
friction = 1, restitution = 0.3}
