003/**
004 * Definition: An entity feature that represents the resulting physical entity subsequent to a cleavage or
005 * degradation event.
006 *
007 * Usage: Fragment Feature can be used to cover multiple types of modfications to the sequence of the physical
008 * entity:
009 * <ul>
010 * <li>    A protein with a single cleavage site that converts the protein into two fragments (e.g. pro-insulin
011 * converted to insulin and C-peptide). TODO: CV term for sequence fragment?  PSI-MI CV term for cleavage site?
012 * <li>    A protein with two cleavage sites that removes an internal sequence e.g. an intein i.e. ABC -&gt; A
013 * <li>    Cleavage of a circular sequence e.g. a plasmid.
014 * </ul>
015 * In the case of removal ( e.g. intron)  the fragment that is *removed* is specified in the feature location
016 * property. In the case of a "cut" (e.g. restriction enzyme cut site) the location of the cut is specified instead.
017 * Examples: Insulin Hormone
