Using m_vector

This is an example showing how to use my dirt-simple m_vector library to create and delete data dynamically. The program comes from this StackOverflow question, where the OP seemed familiar with the C++ STL vector class, but did not know how to accomplish the same thing in C. I feel it best to keep the implementation and interface for a generic container separate from any particular application so that it is reusable.
