Expose query costing through libgrom #14

Closed lordpretzel closed 6 years ago

Internally, GProM uses the database backend to cost queries if this is supported by the backend (implementation is currently limited to Oracle). It would be useful to expose this functionality to the outside world by adding a method to libgprom.

extern long gprom_costQuery(const char *query)
