+  Synopsis    [APIs of the DSD node.]
+
+  Description [The node's type can be retrieved by calling
+  Dsd_NodeReadType(). The type is one of the following: constant 1 node, 
+  the buffer (or the elementary variable), OR gate, EXOR gate, or 
+  PRIME function (a non-DSD-decomposable function with more than two 
+  inputs). The return value of Dsd_NodeReadFunc() is the global function 
+  of the DSD node. The return value of Dsd_NodeReadSupp() is the support 
+  of the global function of the DSD node. The array of DSD nodes
+  returned by Dsd_NodeReadDecs() is the array of decomposition nodes for 
+  the formal inputs of the given node. The number of decomposition entries 
+  returned by Dsd_NodeReadDecsNum() is the number of formal inputs. 
+  The mark is explained below.]
