This contract holds the system variables to manage the state, wether it's the state itself or the thresholds configurations; as well as many `view` functions to access and evaluate it.

* State:
  * System State itself: `States public state = States.AboveCobj;`
  * Global number of RBTC: Complete amount of Bitcoin in the system `uint256 public globalNB = 0;`
  * Configuration variables:
    * PEG: Relation between DOC and US dollar `uint256 public peg = 1;`
    * BPro max discount rate: Reflects the discount spot rate at Liquidation level `uint256 public bproMaxDiscountRate;`
    * Liquidation threshold: `uint256 public liq;`
    * BPro with discount threshold: `uint256 public utpdu;`
    * Liquidation enabled: `bool public liquidationEnabled;`
    * Protected threshold: `uint256 public protected;`

It also defines the State enum options:

```sol
  enum States {
    // State 0
    Liquidated,
    // State 1
    BProDiscount,
    // State 2
    BelowCobj,
    // State 3
    AboveCobj
  }
```
