Token (predict4all 1.0.0 API)

All Known Implementing Classes:

EquivalenceClassToken, SeparatorToken, TagToken, WordToken
```
public interface Token
```
Represent the lowest unit when parsing a text. The unit can be words, but can also a special type : token separator, tags, or equivalence classes.
Token separators are the special character that are used as separators between words in natural language : space, comma, etc... (see Separator)
Equivalence classes are a special "word" tokens that already have a semantic information : they can be date, numbers, etc... (see EquivalenceClass)
