    Class ContractFunctionSelector

    Class to help construct function selectors for Hedera smart contract function calls. Function selectors are the first 4 bytes of the Keccak-256 hash of the function's signature.

    This class provides methods to build function signatures by adding parameters of various Solidity types. It supports all standard Solidity parameter types and their array variants.
