* @short A value based class that hands out QNetworkAccessManager
* appropriately for variable bindings.
*
* NetworkAccessDelegator is an indirection mechanism which takes care of
* the fact that QIODevice instances are injected into the data model by
* having them represented using a URI. managerFor() returns appropriately
* the right network access manager depending on whether the URI refers to
* a variable, or to something else.
*
* The constructor take a pointer to two NetworkAccessDelegator instances.
* First is a generic one, the second is the one which handles variable
* bindings. managerFor() then returns the appropriate one depending on the
* URI.
