for some calculations having the end of the muzzle is extremely helpful:
syntax:
```
unit muzzlePosition muzzleName
```
Example:
```
player muzzlePosition primaryWeapon player
```
The return value can either be ASL, AGL, or in model coordinates.
Alternatively, we could have a `weaponMemoryPointToWorld ` command that supports custom selection names:
```
player weaponMemoryPointToWorld [primaryWeapon player, "usti hlavne"]
```
(the shorter the command name the better!)
