Manage relationship between Model

[stombre]

Path to reference graph;

• Rewamp Relation object to store multiple attributes references
• Work with Field.bindModel to declare reference only when the field have a Model
• Work with ilorm to handle case of reference is a string (could probably wait to the new model to be declared before associate them).
• Add a Field.reference(targetModel, targetField) // or refer to? // to associate a field (in a schema declaration) to another model / field
  Initial work; Add/reference #8

linkedWith:

• linkedWith(model_id)
• linkedWith(model instance)
• linkedWith(query)
• linkedWith(query) multiple (more than one on the same query)
• notLinkedWith: same as linkedWith; opposite operation

Deep relation a =ref=> b =ref=> c (a linkedWith c)

• Resolve deep relation between concept (in Relation class ? Dummy vs A* / Djistra ?)
• Make linkedWith work with deep reference
• Way to overload behavior when resolving complex reference (for handling join operator in SQL eventually)

Issue spotted:

• Manage model reference model more than once. (throw errror at least?)

way to load a reference from an instance (ex: Model.getLinkedModelQuery() (if 1:n) OR Model.getModel() (if 1:1))

• POC (need to explore primary value way?)

Future

• Explore a way to manage relation between different connector
