/**
* @dev Intended to update the TWAP for a token based on accepting an update call from that token.
* expectation is to have this happen in the _beforeTokenTransfer function of ERC20.
* Provides a method for a token to register its price sourve adaptor.
* Provides a function for a token to register its TWAP updater. Defaults to token itself.
* Provides a function a tokent to set its TWAP epoch.
* Implements automatic closeing and opening up a TWAP epoch when epoch ends.
* Provides a function to report the TWAP from the last epoch when passed a token address.

$Ultron is a protocol with two automated core functions: passive yield income and increasing positive volume of transactions. The major goal of Ultron is to achieve the True Burn mechanism (hard coded in the DNA), which allows $Ultron (Burn Address) to continue acquiring tokens and hence raise the token price every time this happens. (Wow, thatβs awesome, and the use case is even better!)
