* @dev Validation of an incoming purchase. Use require statements to revert state when conditions are not met. Use `super` in contracts that inherit from Crowdsale to extend their validations.
* Example from CappedCrowdsale.sol's _preValidatePurchase method:
* super._preValidatePurchase(_beneficiary, _weiAmount);
* require(weiRaised.add(_weiAmount) <= cap);
* @param _beneficiary Address performing the token purchase
* @param _weiAmount Value in wei involved in the purchase
