Log:
- removed the IRelationTool. Actually by 'relation tool' we mean 'relation
storage', so instead of writing:
>>> reltool = IRelationTool(context)
>>> reltool.search(...)
we have:
>>> from cpsskins.utils import getRelationStorage
>>> relations = getRelationStorage(context)
>>> relations.search(...)
the orginal idea was to make it possible to plug in other relation tools
than the default one. This is still possible but this will not be done
at run timei through an adapter lookup, but during configuration time with:
<cpsskins:storage
id="relations"
title="Relation storage"
description="A relation storage contains relations between objects"
class="my.relationengine.RelationStorage" <<<
interface="cpsskins.relations.IRelationStorage"
contains="cpsskins.relations.interfaces.IRelation"
/>
the storage is physically stored in the theme management folder.
