Smart contract (on Polygon) + dAbPI

[Gizmotronn]

https://github.com/signal-k/dabpi/issues/6

Creating a smart contract for an online game (which will interact with Moralis and our own DB for Signal-K/Unity-Demo#5)

• Finish smart contract
• Set up inheritance
• Deploy to rinkeby + Mumbai testnet

I am just calling the tokens "Credits" with shortname "SKK" (SignalKineticsKoin), 'Credit' derives from the currency in Star Wars. Not sure what we'll call the main currency later -> maybe 'gears' or something robotics?? Also, I'm looking into multiple currencies.
