+
+Direct file store.
+
+A direct file store implements a set of the operations to open store, create streams(CStoreWriteStream 
+and CStoreReadStream), set root stream id to the store.
+
+Objects can be externalized to streams represented by class CStoreWriteStream. Once the streams 
+have been closed, they cannot subsequently be changed, i.e. streams cannot be replaced, deleted, 
+extended or changed in any way. 
+
+Existing direct file stores can be opened with this class. Objects can be restored with class 
+CStoreReadStream.
+
+Before closing a new store, the root stream id must be set. After opening an existing store, the 
+first thing done is to look up the root stream id. The root stream can then be opened and data 
+read from the store.
