Measure battery life of the clickers

Once pull request #34 is merged, it would be good to have better measurements of the battery life of the clickers in different scenarios.

• scenario 1:
  PIC32 is executing an infinite while loop. The current consumption is expected to be 22mA, hence the battery life should lie between five days to one week.

• scenario 2:
  PIC32 is constantly sending data over 6LoWPAN to a Ci40. The current consumption is expected to be in range 75-95mA.

The 3.3V pin and GND pin should be connected to the Ci40. The Ci40 runs a program to measure how long the 3.3V pin is high. This can be done quite easily using gpio_monitor of LetMeCreate.

In progress...

@francois-berder-imgtec what's left to do here?

@Shpinkso Waiting...
The clicker is currently running and the 3.3V and GND are connected to one of my Ci40 on my desk. Unfortunately, I could not get results earlier as my program crashed at some point, and the program failed to detect that the 3.3V line was low. I've change my program to make it more robust and hopefully by Monday, I should get the first result.

cool thanks

Result of scenario 1: 2 days, 22 hours 46 minutes
The clicker was using 35mA in sleep.
