We need define the contracts architecture for the DEX.

These are the features that we need to implement:

• DEX'es are mainly formed by investors adding their tokens in liquidity pools;
• Each liquidity pool are formed by a pair of tokens that will be traded with each other;
• The liquidity added by investors will be used by traders to swap between two tokens;
• The trade by a trader must match an existing liquidity pool and obey the amount present in these liquidity pools;
• A successful trade will transfer the "bought" token from the liquidity pool to the trader wallet;
• A successful trade will transfer the "sold" token from the trader wallet to the liquidity pool;
• An investor can withdraw it's token pair from the liquidity pool, in the same proportion as the liquidity pool has defined as balanced (for first iteration, we may skip changing the proportion as trades are made into the liquidity pool / prices changes);
