I am very new to Ethereum and don't really understand the problem spec very well, so bear with me.
There is a function named GetVotesCount() in the contract MordorVote which I must limit to only being called by a 'vote master'. How can I determine who is calling a function in the contract?
Also, when I invoke a function in Embark, I get a hex string returned, but not whatever the function returns. How can I find out what a function is returning?
