     DMDARestoreAdicMFArray - Restores an array of derivative types for a DMDA.
          
     Input Parameter:
+    da - information about my local patch
-    ghosted - do you want arrays for the ghosted or nonghosted patch?

     Output Parameters:
+    ptr - array data structure to be passed to ad_FormFunctionLocal()
.    array_start - actual start of 1d array of all values that adiC can access directly
-    tdof - total number of degrees of freedom represented in array_start

     Level: advanced
