Zephyr Program for Soroswap AMM

This program will create 3 tables as defined in the zephyr.toml file:

• The Soroswap Router Events Table ssw_rt_ev
• The Soroswap Pairs Table ssw_pairs
• The Soroswap Reserves Changes Table ssw_rs_ch

These tables are filled like this:

• The Router Events Table is easy, because it records every event in the SoroswapRouter contract, nothing more, nothing less. It records every thime there is a remove (remove liquidity), add (add liquidity) and swap.

router::events::handle_contract_events(&env, filtered_router_events_with_txhash);

• The Soroswap Pairs Table is being filled evey time there is a new_pair event in the SoroswapFactory contract.

factory::events::handle_contract_events(&env, filtered_factory_events_with_txhash);

And finally, after we have both the Router Events Table and the Pairs Table, up to dated, if there is any event emited by any of our pairs, we will handle all sync events.

pairs::events::handle_contract_events(&env, pair_contract_events, pair);

The sync event at a Liquidity Pool level it gets executed after every deposit, swap or withdraw at the SoroswapPair contract. Every time there is a sync event, the corresponding row of the Soroswap Pair Table gets updated!
