Proposing an Index

First step in the basket creation process is for an index publisher to propose a new index. The proposer calls proposeBasketLicense on the factory contract. This contract takes the following inputs:

tokenName	Full name of the basket token
tokenSymbol	Symbol for the basket token
tokens	array of token contract addresses that will be included in the index
weights	the amount of tokens (uint256) in 1 basket token upon basket's creation

The protocol will assign an idNumber to the proposal.
