  @title Aave-AMPL ERC20 AToken
  @dev Implementation of the interest bearing AMPL token for the Aave protocol
  @author AmpleforthOrg

  The AMPL AToken externally behaves similar to every other aTOKEN. It always maintains a 1:1 peg with
  the underlying AMPL. The following should always be true.

  1) At any time, user can deposit x AMPLs to mint x aAMPLs.
     Total aAMPL supply increases by exactly x.
  2) At any time, user can burn x aAMPLs for x AMPLs.
     Total aAMPL supply decreases by exactly x.
  3) At any time, userA can transfer x aAMPLs to userB.
     userA's aAMPL balance reduces by X.
     userB's aAMPL balance increases by X.
     Total aAMPL supply exactly remains same.
  4) When AMPL's supply rebases, only the 'unborrowed' aAMPL should rebase.
      * Say there are 1000 aAMPL, and 200 AMPL is lent out. AMPL expands by 10%.
        Thew new aAMPL supply should be 1080 aAMPL.
      * Say there are 1000 aAMPL, and 200 AMPL is lent out. AMPL contracts by 10%.
        Thew new aAMPL supply should be 920 aAMPL.
  5) When AMPL's supply rebases, only the part of the balance of a user proportional to  the available liquidity ('unborrowed') should rebase.
      * Say a user has deposited 1000 AMPL and receives 1000 aAMPL, and
        20% of the total underlying AMPL is lent out. AMPL expands by 10%.
        The new aAMPL user balance should be 1080 aAMPL.
      * Say a user has deposited 1000 AMPL and receives 1000 aAMPL, and
        20% of the total underlying AMPL is lent out. AMPL contracts by 10%.
        The new aAMPL supply should be 920 aAMPL.
  6) The totalSupply of aAMPL should always be equal to (total AMPL held in the system) + (total principal borrowed denominated in AMPL) + (interest)


  Generic aToken:

  ATokens have a private balance and public balance.

  ```
    # _balances[u] and _totalSupply from contract storage.
    Balance(u) = _balances[u] . I
    TotalSupply(supply) = _totalSupply . I
  ```

  The internal (fixed-supply) balance and totalSupply are referred to as balanceScaled and scaledTotalSupply
  and correspond to the principal deposited.

  The external (elastic-supply) balance and totalSupply correspond to the principal + interest.


  AAMPL:

  AAMPL tokens have an additional scaling factor (multiplier) on top of the existing AToken structure.
  Thus they have 2 private balances and 1 public balance.

    * The internal (fixed-supply) balance and totalSupply are referred to as balanceInternal and
      totalSupplyInternal, used for book-keeping.

    * The internal (elastic-supply) balance and totalSupply are referred to as balanceScaled and
      scaledTotalSupply and correspond to the principal deposited.

    * The external (elastic-supply) balance and totalSupply correspond to the principal + interest.

  ```
    # _balances[u] and _totalSupply from contract storage.

    Balance(u) = ( _balances[u] . λ ) . I

    where,

    * _balances[u] is called userBalanceInternal, raw value in contract's storage

    * (_balances[u] . λ) is called userBalanceScaled, aka principal deposited

    * (_balances[u] . λ) . I  is the public userBalance, aka user's principal + interest

    * I is AAVE's interest rate factor

    * λ is the AAMPL scaling factor


    AND

    TotalSupply(u) = ( _totalSupply[u] . λ ) . I

    * _totalSupply[u] is called totalSupplyInternal, raw value in contract's storage

    * (_totalSupply[u] . λ) is called scaledTotalSupply, aka principal deposited

    * (_totalSupply[u] . λ) . I  is the public totalSupply, aka principal + interest

    * I is AAVE's interest rate factor

    * λ is the AAMPL scaling factor

  ```

  The AAMPL scaling factor λ is calculated as follows:

  ```
    * Λ - Ampleforth co-efficient of expansion (retrieved from the AMPL contract)

    scaledTotalSupply = (totalGonsDeposited - totalGonsBorrowed) / Λ + totalPrincipalBorrowed

    λ = scaledTotalSupply / totalSupplyInternal
  ```

  Additions:
    * The AAMPLToken stores references to the STABLE_DEBT_TOKEN,
      and the VARIABLE_DEBT_TOKEN contracts to calculate the total
      Principal borrowed (getAMPLBorrowData()), at any time.
    * On mint and burn a private variable `_totalGonsDeposited`
      keeps track of the scaled AMPL principal deposited.
