NANO100: Use CMSIS DSP library in NANO100 series microcontroler

1.Build the arm_cortexM0l_math.lib
   The source project is located on
   After build you will find the arm_cortexM0l_math.lib in
2.Use the arm_cortexM0l_math.lib copy the Template project. And add ARM_MATH_CM0 in 
   Preprocessor Symbols

3.Add the #include "arm_math.h"  and  arm_cortexM0l_math.lib in Template project.

4.Now you can use the CMSIS DSP library to optimized the math function!
