/**
 * Implements the Re-sleeving mechanic for BitNode-10.
 * This allows the player to purchase and "use" new sleeves at VitaLife.
 * These new sleeves come with different starting experience and Augmentations
 * The cost of these new sleeves scales based on the exp and Augs.
 *
 * Note that this is different from the "Sleeve mechanic". The "Sleeve" mechanic
 * provides new sleeves, essentially clones. This Re-sleeving mechanic lets
 * the player purchase a new body with pre-existing Augmentations and experience
 *
 * As of right now, this feature is only available in BitNode 10
