/**
|
|
* @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
|
|
* MintedCrowdsale - assumes the token can be minted by the crowdsale, which does so
|
|
* when receiving purchases.
|
|
*
|
|
* After adding multiple features it's good practice to run integration tests
|
|
* to ensure that subcontracts works together as intended.
