DSValue

Simple price feed setter and getter

1. Summary
This is a simple contract where authorized addresses can set a price and anyone can read it.
2. Contract Variables & Functions
Variables
isValid - boolean that signals whether the currently stored value is valid (greater than zero) or not
medianPrice - the current price feed
Modifiers
auth - modifier that checks whether an address can set the result. Inherited from ds-thing.
Functions
getResultWithValidity() external view returns (bytes32, bool) - returns result and isValid
read() external view returns (uint256) - getter that only returns the result
updateResult(newResult: bytes32) - set a new result
restartValue() - set isValid to false
3. Walkthrough
Authorized functions can set a new medianPrice by calling updateResult. Anyone can read the medianPrice or read both the medianPrice and whether it isValid by calling read orgetResultWithValidity.
