The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

	## Overview
	The simplest structure of a token sale consists of a sale contract and token contract.

	The sale contract is responsible for such logic including but not limited to:
	- the duration of the sale (typically in blocks)
	- the addresses allowed to participate in the sale
	- the exchange rate of ether to tokens, often as a factor of time
	- the ether reserve and hard cap amounts

	The token contract is responsible for such logic including but not limited to:

	pragma solidity 0.4.24;

	import './SimpleRestrictedToken.sol';

	contract MyRestrictedToken is SimpleRestrictedToken {
	string public name;
	string public symbol;
	uint public decimals;
	uint public totalSupply;
