// 1 - Accept profits sent as ETH to the contract.
// 2 - Allow shareholders to withdraw their fair portion of the profits based on the % they own at the time of the profits' sharing.
// 3 - Allow a shareholder to transfer his or her stake in the contract to someone else.
// 4 - Allow all shareholders to hold a vote:
// 		- if passing 51% agreement, allows them to dilute all of their own shares and issue a % of new equity at a valuation that is equal to 100 multiplied by the profits accrued during the previous month
// 5 - Allow new users to buy the new equity at the offered price following a successful vote, to become shareholders themselves.
// 6 - Allow all interaction with the smart contracts to occur via the browser, including letting shareholders check their balance of profits to be paid.
