Some utility work....

- Implement std::string DataProcess::getStdStringFromSizeT(const size_t & number).

- Change prototype of DataProcess::Data_Object DataProcess::getStringFromSizeT(size_t number) to, DataProcess::Data_Object DataProcess::getStringFromSizeT(const size_t & number) and clean it up abit.

- Implement template<typename T> void removeFromVector(std::vector<T> & container, const size_t & offset)

- Update copyright year on DataProcess.cpp and DataProcess.h.
