/// @title PriceAndFeeCalculator
/// @notice Calculates and manages unit price and fees for multiple vaults that share the same numeraire token. Acts as
/// a price oracle and fee accrual engine. Vault registration workflow is:
/// 1. Register a new vault with registerVault()
/// 2. Set the thresholds for the vault with setThresholds()
/// 3. Set the initial price state with setInitialPrice()
/// Once registered, a vault can have its price updated by an authorized entity. Vault owners set thresholds for price
/// changes, update intervals, and price age. If a price update violates thresholds (too large change, too soon, or too
/// old), the vault is paused. Paused vaults dont accrue fees and cannot have their price updated until they are
/// unpaused by the vault owner. Accrues fees on each price update, based on TVL and performance since last update
/// Supports conversion between vault units, tokens, and numeraire for deposits/withdrawals. All logic and state is
/// per-vault, supporting many vaults in parallel. Only vault owners can set thresholds, and vault owners or their
/// accountants can pause/unpause their vaults. Integrates with an external oracle registry for token price conversions
