resource unit

Contains base classes for resource handling

This unit contains base classes needed to work with resources.

Single resources are represented by an instance of a TAbstractResource descendant. They are grouped in a TResources instance which can be read (written) to (from) a stream via a TAbstractResourceReader (TAbstractResourceWriter) descendant.

TGenericResource provides a basic implementation of TAbstractResource.
