Code sample for MyCrowdsaleDeployer causes TypeError:
```
browser/MyCrowdsaleDeployer.sol:21:13: TypeError: Invalid type for argument in function call. 
Invalid implicit conversion from address to contract IERC20 requested.
            address(token)            // the token
            ^------------^
```
Change: 
```solidity

```
To:
```solidity
token   // the token
```
