* \brief Convert floating and fixed point numbers to strings
*
* This class uses the double-conversion library to floating point and
* fixed point numbers to ASCII versions that are represented without
* numerical precision errors.
*
* Typical use:
* \#include "itkNumberToStrong.h"
* NumberToString<float> convert;
* float a = 1.0f/3.0f;
* std::cout << convert(a) << std::endl;
