**Shard**

Creates a shard child contract that contains the contributor shares, contribution, claims, claim time,  and whitelist status, with operations such as **redeem** and **withdraw.** Whitelisting in shard requires to initialize a child contract for 0.05 TON for every address to be whitelisted.
