/**
 * @brief Register a function to execute on boot and (optionally) in other situations
 *
 * @param initFunc The function to execute
 * @param updatePaths Strings to specify additional situations in which to execute the function
 *
 * ### Examples:
 *
 * #### Execute function `bar` on boot
 *
 * ```cpp
 * static RegisterShipInitFunc foo(bar);
 * ```
 *
 * #### Execute function `bar` on boot and when the CVar `baz` might have changed
 *
 * ```cpp
 * static RegisterShipInitFunc foo(bar, { "baz" });
 * ```
 *
 * #### Execute function `bar` on boot and when `IS_RANDO` might have changed
 *
 * ```cpp
 * static RegisterShipInitFunc foo(bar, { "IS_RANDO" });
 * ```
 *
 * ### Additional Information:
 *
 * To get a better sense of when your function will be executed
 * you can look for `ShipInit::Init` calls throughout the codebase
