Missing support for SQL operator 'OVERLAPS'

[d2a-raudenaerde]

In SQL it is possible to do something like this:

select 'yes' from dual where (sysdate-5,sysdate) overlaps (sysdate-2,sysdate-1) (interval5.sql)

JsqlParser currently does not support this.

I started a Discussion on how it could be implemented: #1600
