ISSUE-19 (Reuse SQL query as sub-query): Reuse a SQL query as a sub-query  [R2RML]

Reuse a SQL query as a sub-query under multiple TriplesMaps.

For example, there may be a repeated sub-query that is used by several
queries. Rather than copy-and-paste the query multiple times, it is
desirable to write it once and join it into several other queries. In
particular, consider the case where the mapping process is not allowed to
make changes to the database (e.g. by adding a view to the database).

A possible solution is to allow a logical table (i.e. query) to be built in
the mapping from sub-logical-tables.
