// ----------------------------------------------------------------------------
// The SENC Token Sale Whitelist Contract is designed to facilitate the features:
//
// 1. Track whitelisted users and allocations
// Each whitelisted user is tracked by its wallet address as well as the maximum
// SENC allocation it can purchase.
//
// 2. Track batches
// To prevent a gas war, each contributor will be assigned a batch number that
// corresponds to the time that the contributor can start purchasing.
//
// 3. Whitelist Operators
// A primary and a secondary operators can be assigned to facilitate the management
// of the whiteList.
