************************* [Low Healer Custom AI] *******************************
    This is a custom AI file for Low Cleric's.

    This is a cleric - It heals the nearest ally, after itself (if under
    50% HP) that has under 50% HP.

    It doesn't cast spells other then healing ones, however.
************************* [History] ********************************************
    1.3 - Added as sample
************************* [Workings] *******************************************
    Uses Combat_GetAITargetObject, to see if we saw something new or something.
    It will only attack seen things.

    Then we do:

    - Healing (at 50%) using best
    - Heal allies
    - Potions (using random % below)
    - Use turning
    - Attack in melee or range.
