Overloaded template function to compare value with zero. It returns true if value is equal(or nearly equal) to zero. For complex object comparison takes place for all components and function return true only if all of them are zero(or close to zero).

template<class TYPE>
constexpr bool IsZero(const TYPE a); // Check whether argument is zero
template<class TYPE>
constexpr bool IsZero(const TYPE a, const TYPE tolerance = Tolerance<TYPE>); // Check whether argument is zero. For float values. Uses absolute comparison
