/**
  The Proxy contract implements delegation of calls to other contracts (`implementations`), with
  proper forwarding of return values and revert reasons. This pattern allows retaining the contract
  storage while replacing implementation code.

  The following operations are supported by the proxy contract:

  - :sol:func:`addImplementation`: Defines a new implementation, the data with which it should be initialized and whether this will be the last version of implementation.
  - :sol:func:`upgradeTo`: Once an implementation is added, the governor may upgrade to that implementation only after a safety time period has passed (time lock), the current implementation is not the last version and the implementation is not frozen (see :sol:mod:`FullWithdrawals`).
  - :sol:func:`removeImplementation`: Any announced implementation may be removed. Removing an implementation is especially important once it has been used for an upgrade in order to avoid an additional unwanted revert to an older version.

  The only entity allowed to perform the above operations is the proxy governor
  (see :sol:mod:`ProxyGovernance`).

  Every implementation is required to have an `initialize` function that replaces the constructor
  of a normal contract. Furthermore, the only parameter of this function is an array of bytes
  (`data`) which may be decoded arbitrarily by the `initialize` function. It is up to the
  implementation to ensure that this function cannot be run more than once if so desired.

  When an implementation is added (:sol:func:`addImplementation`) the initialization `data` is also
  announced, allowing users of the contract to analyze the full effect of an upgrade to the new
  implementation. During an :sol:func:`upgradeTo`, the `data` is provided again and only if it is
  identical to the announced `data` is the upgrade performed by pointing the proxy to the new
  implementation and calling its `initialize` function with this `data`.

  It is the responsibility of the implementation not to overwrite any storage belonging to the
  proxy (`ProxyStorage`). In addition, upon upgrade, the new implementation is assumed to be
  backward compatible with previous implementations with respect to the storage used until that
  point.

/**
  The Proxy contract is governed by one or more Governors of which the initial one is the
  deployer of the contract.

  A governor has the sole authority to perform the following operations:

  1. Nominate additional governors (:sol:func:`proxyNominateNewGovernor`)
  2. Remove other governors (:sol:func:`proxyRemoveGovernor`)
  3. Add new `implementations` (proxied contracts)
  4. Remove (new or old) `implementations`
  5. Update `implementations` after a timelock allows it

  Adding governors is performed in a two step procedure:

  1. First, an existing governor nominates a new governor (:sol:func:`proxyNominateNewGovernor`)
  2. Then, the new governor must accept governance to become a governor (:sol:func:`proxyAcceptGovernance`)

  This two step procedure ensures that a governor public key cannot be nominated unless there is an
  entity that has the corresponding private key. This is intended to prevent errors in the addition
  process.

  The governor private key should typically be held in a secure cold wallet or managed via a
  multi-sig contract.
