-/// @author Jordi Baylina
-/// @dev The SNTPlaceholder contract will take control over the SNT after the contribution
-///  is finalized and before the Status Network is deployed.
-///  The contract allows for SNT transfers and transferFrom and implements the
-///  logic for transferring control of the token to the network when the offering
-///  asks it to do so.
