* \brief Initialize system
*
* This function will call the various initialization functions within the
* system namespace. If a given optional system module is not available, the
* associated call will effectively be a NOP (No Operation).
*
* Currently the following initialization functions are supported:
* - System clock initialization (via the SYSTEM CLOCK sub-module)
* - Board hardware initialization (via the Board module)
* - Event system driver initialization (via the EVSYS module)
* - External Interrupt driver initialization (via the EXTINT module)
