ITK/Examples

These are fully independent, compilable examples. There is significant overlap in the examples, but they are each intended to illustrate a different concept and be fully stand alone compilable. Please add examples in your areas of expertise!

Simple Operations

Example Name	ITK Classes Demonstrated	Description
Distance between two points	Point
Create a vector	Vector
Create a covariant vector	CovariantVector
Variable length vector	VariableLengthVector	main() works properly, but neither conversion seems to work.
