Levi-Civita Symbol

This is an implementation of the Levi-Civita symbol, known as "epsilon i j k"

This is an implementation of the Levi-Civita symbol, also known as the permutation tensor, or "epsilon i j k". The function supports not just three but two, four, five etcetera indices. It is fairly fast. Most of the file is a test driver which can be deleted. To see how it works just type "levi_civita".
