/**
 * @title Immutable Create2 Contract Factory
 * @author 0age
 * @notice This contract provides a safeCreate2 function that takes a salt value
 * and a block of initialization code as arguments and passes them into inline
 * assembly. The contract prevents redeploys by maintaining a mapping of all
 * contracts that have already been deployed, and prevents frontrunning or other
 * collisions by requiring that the first 20 bytes of the salt are equal to the
 * address of the caller (this can be bypassed by setting the first 20 bytes to
 * the null address). There is also a view function that computes the address of
 * the contract that will be created when submitting a given salt or nonce along
 * with a given block of initialization code.
 * @dev This contract has not yet been fully tested or audited - proceed with
 * caution and please share any exploits or optimizations you discover.

   * @dev Create a contract using CREATE2 by submitting a given salt or nonce
   * along with the initialization code for the contract. Note that the first 20
   * bytes of the salt must match those of the calling address, which prevents
   * contract creation events from being submitted by unintended parties.
   * @param salt bytes32 The nonce that will be passed into the CREATE2 call.
   * @param initializationCode bytes The initialization code that will be passed
   * into the CREATE2 call.
   * @return Address of the contract that will be created, or the null address
   * if a contract already exists at that address.
