bool IsInUse(const Double32_t* p) const

       Function to check if a vector is sharing same memory location of the passed pointer
       This function is used by the expression templates to avoid the alias problem during
       expression evaluation. When  the vector is in use, for example in operations
       like V = M * V, where M is a mtrix, a temporary object storing the intermediate result is automatically
       created when evaluating the expression.

std::ostream& Print(ostream& os) const

 used by operator<<()
