Relations names should not be mandatory to match resource table

[rafinskipg]

corbelDriver.resources
    .relation('resourceName', sourceId, 'relationName')
   .add(null, data);

That would create a relation called 'resourceName_relationName'.

Instead of this, the relation created should be relationName. And if you want to use a different resource for the relation:

corbelDriver.resources
    .relation('resourceName', sourceId, 'relationName')
   .add(RESOURCE_ID, data);

Right now it is looking for another resource called relationName for finding that RESOURCE_ID.
Instead of this add another param, resourcesDest or something like that

corbelDriver.resources
    .relation('resourceName', sourceId, 'relationName', 'resourceNameDestination`)
   .add(RESOURCE_ID, data);
