Represent a n-dimensional index in a n-dimensional image.
Index is a templated class to represent a multi-dimensional index, i.e. (i,j,k,...). Index is templated over the dimension of the index. ITK assumes the first element of an index is the fastest moving index.
For efficiency sake, Index does not define a default constructor, a copy constructor, or an operator=. We rely on the compiler to provide efficient bitwise copies.
Index is an "aggregate" class. Its data is public (m_Index) allowing for fast and convenient instantiations/assignments.
The following syntax for assigning an index is allowed/suggested:
Index<3> index = {{5, 2, 7}};
The double braces {{ and }} are needed to prevent a compiler warning about a partly bracketed initializer.
