/**
* This package contains all objects to use a Column Family API. This API gonna focus in domain, in other words,
* ubiquitous language. A column family is a NoSQL object that contains columns of related data. It is a tuple (pair)
* that consists of a key-value pair, where the key is mapped to a value that is a set of columns.
* In analogy with relational databases, a column family is as a "table", each key-value pair being a "row".
* Each column is a tuple (triplet) consisting of a column name, a value, and a timestamp. In a relational
* database table, this data would be grouped together within a table with other non-related data.
