## Warps control

Control Module - Warps - Stores warps for each force.

### Usage

    -- Making a new spawn warp
    local player = game.player
    local force = player.force
    local spawn_id = Warps.add_warp(force.name,player.surface,player.position,player.name,'Spawn')

    Warps.set_spawn_warp(spawn_id, force)
    Warps.make_warp_tag(spawn_id)

    -- Making a new warp with a warp area
    local player = game.player
    local force = player.force
    local warp_id = Warps.add_warp(force.name,player.surface,player.position,player.name)

    Warps.make_warp_area(warp_id)
    Warps.make_warp_tag(warp_id)
