* @title Metamorphic Contract
* @author 0age, derived from cloner contract by @mhswende
* @notice This contract will create a metamorphic contract, or an upgradeable
* contract that does not rely on a transparent proxy, when deployed using
* CREATE2. It expects the deployer to provide a getImplementation() function
* that will return an implementation address, which it will then clone and
* deploy. Unlike with upgradeable transparent proxies, the state of a
* metamorphic contract will be wiped clean with each upgrade. With great power
* comes great responsibility - implement appropriate controls and educate the
* users of your contract if it will be interacted with!

##### SUMMARY #####
#
# to brick a user proxy, you can upgrade to this contract then call the proxy:
# https://etherscan.io/address/0x00000000008fe2c0c1795fe9a8e2c1d3f913b35d#code
#
# Step 1: find the proxy for the account
# proxy registry: 0xa5409ec958C83C3f309868babACA7c86DCB077c1
# call: proxies(address) where address = user's account
#
# Step 2: upgrade the proxy and call it to renounce ownership
