Rename: "initializeLog" -> "InititateLog"

Renamed some HSIT slave functions and files for clarity:
'initializeLog()' -> 'initiateLog()'
'initializeSlave()' -> 'initiateSlaveLog()'
'finalizeSlave()' -> 'terminateSlaveLog()'
"initialize_slave.h" -> "initiate_slave_log.h"
"finalize_slave.h" -> "terminate_slave_log.h"
