template<typename ContainerType, typename ElementType, typename SizeType>  
class TIndexedContainerIterator

Generic iterator which can operate on types that expose the following:

A type called ElementType representing the contained type.
A method SizeType Num() const that returns the number of items in the container.
A method bool IsValidIndex(SizeType index) which returns whether a given index is valid in the container.
A method T& operatorSizeType index which returns a reference to a contained object by index.
A method void RemoveAt(SizeType index) which removes the element at index

	Type	Name	Description
		TIndexedContainerIterator ( ContainerType& InContainer, SizeType StartIndex )

Type	Name	Description
SizeType	GetIndex ()	Returns an index to the current element.
void	RemoveCurrent ()	Removes current element in array.
void	RemoveCurrentSwap ()	Removes current element in array by swapping it with the end element and popping it from the end.
void	Reset ()	Resets the iterator to the first element.
void	SetToEnd ()	Sets the iterator to one past the last element.

Type	Name	Description
TIndexedContainerIterator	operator- ( SizeType Offset )
TIndexedContainerIterator &	operator-- ()	Moves iterator to the previous element in the container.
TIndexedContainerIterator	operator-- ( int )
	operator bool ()	Conversion to "bool" returning true if the iterator has not reached the last element.
bool	operator!= ( const TIndexedContainerIterator& Rhs )
ElementType &	operator* ()
TIndexedContainerIterator	operator+ ( SizeType Offset )
TIndexedContainerIterator	operator++ ( int )
TIndexedContainerIterator &	operator++ ()	Advances iterator to the next element in the container.
TIndexedContainerIterator &	operator+= ( SizeType Offset )	Iterator arithmetic support
TIndexedContainerIterator &	operator-= ( SizeType Offset )
bool	operator== ( const TIndexedContainerIterator& Rhs )
ElementType *	operator-> ()
