DESCRIPTION
This component creates a Mallet instance object.
This represents a machine learning 'example' to be used in training, testing or performance of various machine learning algorithms.

'Data' holds the data represented by the instance, 'target' is often a label associated with the instance, 'name' is a short identifying name for the instance a(such as a filename), and 'source' is human-readable source information, (such as the original text).
