ArxTypeTraits

C++ type_traits for Arduino which cannot use it as default

Features

• automatically use standard library first if the boards can
• if standard library is not enough (e.g. only C++11 is available), add missing parts listed below
• works almost all Arduino platforms (Let me know if you have errors)
• compatible with ArduinoSTL or other uClibc++ libraries
  • thx @matthijskooijman
