Token class

A Token represents a term (word) present in a text source:

• term is the term that will be looked up in the index;
• termPosition is the zero-based position of the term in an ordered list of all the terms in the source text;
• n is the number of terms in the n-gram; and
• zone is the nullable name of the zone the term is in.
