16 /** This module is responsible for calling all init functions.
17 *
18 * It is also responsible for setting up all scheduled functions for now.
19
20 * Idea: change import direction so this module adds all init functions. All init functions are
21 * wrapped in another function before being run in a thread (i.e. run indirectly). Functions fail
22 * either by throwing an exception or by returning a boolean. Functions may take parameters, e.g.
23 * "out cleanupFunc[]". */
