2) Exposed APIs that are documented in the confluence page
   https://confluence.automotivelinux.org/display/SPE/Speech+EG+Architecture
3) Implemented 39 unit tests based on GTest framework to test all the low
level components of VSHL binding.
4) Implemented a HTML5 based VSHL API tester application to test VSHL APIs.

API specification:
https://confluence.automotivelinux.org/display/SPE/Speech+EG+Architecture#SpeechEGArchitecture-HighLevelVoiceService
