Moving to C++14

[wateret]

I would like to move to C++14, unless there is good reason for not doing this. We're currently on C++11.

Required compiler versions for C++14

• GCC 5.0 or higher
• Clang 3.4 or higher

Portability

• Ubuntu 14.04 : AFAIR default C++ compiler is gcc 4.x
• Ubuntu 16.04 or higher : OK
• Raspberry Pi 2 Ubuntu ??.??
• Other OS (far far far... future)
  • Android : AFAIR NDK toolchain is Clang 4 or higher
  • iOS : Not checked yet, but probably no problem

@seanshpark Can you check your environment please?

Sorry for late response. I'll check today :)
As current RPi build is based on Ubuntu 16.04, there will be no problem :)
