Linkit ONE - 2. example project

1. Create and Run Your First Sketch
    A basic project which can blink LED. Easy to make it.
2. Using HTTP Tutorial
    A basic project which can
      a. connect to wifi router
      b. HTTP GET
      c. HTTP POST
    Just follow the instruction, did not face any problem.
3. Car Tracker Tutorial
    In this project, we can learn how to use
      a. GPS module
      b. GPRS module
      c. MCS(MediaTek Cloud Sandbox)
    This project will use MCS(MediaTek Cloud Sandbox) service to trace GPS/Speed data which upload by Linkit ONE. Sample code.
    There has some compiler error in my environment, it may related to Arduino or SDK version.
    So, I fix them and also made some change that I want, commit to my GitHub.

基本上，只有CarTracker要動點手，剩下都是直接就可以跑。
CarTracker還用到MCS, 可以把板子的資料往雲端送。
