    WALLET LIMITS
 
    Wallets are limited in two ways. The amount of tokens that can be purchased in one transaction
    and the total amount of tokens a wallet can buy. Limiting a wallet prevents one wallet from holding too
    many tokens, which can scare away potential buyers that worry that a whale might dump!
 
    IMPORTANT
 
    Solidity can not process decimals, so to increase flexibility, we multiple everything by 100.
    When entering the percent, you need to shift your decimal two steps to the right.
 
    eg: For 4% enter 400, for 1% enter 100, for 0.25% enter 25, for 0.2% enter 20 etc!
