/**
* @title SampleCrowdsale
* @dev This is an example of a fully fledged crowdsale.
* The way to add new features to a base crowdsale is by multiple inheritance.
* In this example we are providing following extensions:
* CappedCrowdsale - sets a max boundary for raised funds
* RefundableCrowdsale - set a min goal to be reached and returns funds if it's not met
*
* After adding multiple features it's good practice to run integration tests
* to ensure that subcontracts works together as intended.
