basic solidity

	Solidity lets you program on Ethereum, a blockchain-based virtual machine that allows the creation and execution of smart contracts, without needing centralized or trusted parties.
	Solidity is a statically typed, contract programming language that has similarities to Javascript and C. Like objects in OOP, each contract contains state variables, functions, and common data types. Contract-specific features include modifier (guard) clauses, event notifiers for listeners, and custom global variables.
	Some Ethereum contract examples include crowdfunding, voting, and blind auctions.
	As Solidity and Ethereum are under active development, experimental or beta features are explicitly marked, and subject to change. Pull requests welcome.
	// First, a simple Bank contract
	// Allows deposits, withdrawals, and balance checks

	// simple_bank.sol (note .sol extension)
	/* ** START EXAMPLE ** */
