1. How to get an instance which will permit the call of endSale()?
2. How to get the Ether from the sale contract?

I took the ABI from the token sale json and the network address and got an instance of the token sale contract. From there I was able to call endSale().

But I just get an error. The account I am using on Geth is the admin account.

var TokenContract = web3.eth.contract(abi)
var tokenInstance = TokenContract.at('address')

> tokenInstance.endSale()
Error: invalid address

The solution to the above error is:

web3.eth.defaultAccount = web3.eth.accounts[0]

Make sure to check the repo for code to transfer the balance in Ether.
