This Lua library is intended to be used if you need to keep track of gears. It can also keep track of teams and clans and as an extra functionality it can also store variables for a gear, team or clan.

To set it up you need to add some hooks in different events. The hooks `trackGear` and `trackDeletion` to `onGearAdd` and `onGearDelete` respectively. It is strongly recommended to only track the gears you are interested in as, especially with snow on, the amount of gears can go up high and that will slow down the script. To keep track of teams you need to keep track of `gtHedgehog` and `gtResurrector` (if resurrection might be used) and add `trackTeams` to `onGameStart`.

If you want to call a function on a couple of gears you will have to call the “`runOn`” functions. To these you will pass the function you want to be run as a variable to the function.

These functions must be called to start tracking stuff. *IMPORTANT:* The other functions will only work on tracked objects. So make sure you track the things you care about.

For tracked gears, teams and clans, you can assign an arbitrary number of values. Each tracked object has a simple key-value storage. This means, a tracked object has an arbitrary number of keys, each of which holds one arbitrary value. Any data type (besides `nil`) can be used for keys and values. Initially, all keys have the value `nil`.
