Discovered a bug in the reflection system during the copy of objects.
The properties need to be refreshed after copy of objects.
Bug eliminated with the check of the use_count of the shared_ptr<Class>
m_reflectionObject. The operations of select, insert, update were
implemented for the sqlite database.
System of creation of the reflection object improved. Added a method for
deletion of objects.
The select functionalities were improved with options to specify the
orderby, limit and offset.
