Automatically create relations

[steffendsommer]

Since we're already annotating relations, I think it makes sense to have Sourcery create relations. E.g. in the case of (inside Employee.swift):

// sourcery: preparation = foreignId, unique = false, foreignTable = Company
internal var companyId: Identifier?

Then it could create an extension on Employee with a property called company which would return the parent. Similarly it could create an extension on Company with a property called employees which would return the children.

We could consider if it makes sense to have an annotation to indicate 1-1 relations so instead of returning all the children it would return the first children.

It would be great with an annotation that specified whether the results of the extension should be included in makeJSON

Currently you're able to annotate your struct/class with ignoreJSONConvertible to avoid the JSONConvertible extension being created. Further you can annotate with ignoreJSONConvertible on your properties to exclude specific properties from the JSONConvertible extension.

Is this what you need?
