Unable to create pivot tables with attributes

[alar77]

In line 91 of Processor/RelationProcessor a table is recognized as pivotat for a many to many relations (and then included as belongToMany) only if it only has 2 columns.
This makes impossible to store attributes on relation:

if (count($foreignKeys) === 2 && (count($table->getColumns()) === 2))

What about considering a table pivot also if it has exactly 2 primary keys like in

if (count($foreignKeys) === 2 && (count($table->getColumns()) === 2) or count($primaryKeys)===2)) {

Also, maybe the created_at and updated_at columns could be ignored and not counted
