/** 
*   A simple structure which holds the names of all resources & styles used in a doc or part of a document.
*   Also holds pointers to the doc's fontset and colorset.
*   The names are stored as a QMap<QString,QString>. When a doc is queried for it's used resources, these
*   maps get an entry  (nam -> nam) for each used resource 'nam'. You can replace resources consistently by
*   changing these maps and asking the doc to use the altered maps to change all old names to the new one.
*   Operations:
*   - getNamedResources(ResourceCollection& rsc)              ... fills 'rsc' with identity mappings for used resources
*   - replaceNamedResources(const ResourceCollection& maps)   ... uses 'maps' to change old names to new names
*   - redefineNamedResources(const ResourceCollection& defs)  ... uses the definitions in 'defs' to overwrite/add resources
*   - makeNamedResourcesUnique(ResourceCollection& other)     ... changes mapping in 'other' to unique names
*   Merge options:  keep old def, keep new def, rename new resource to unique name
