+    Class for applying a set of transforms to a given ooopy object.
+    The transforms are applied to the specified file in priority
+    order. When applying transforms we have a mechanism for
+    communication of transforms. We give the transformer to the
+    individual transforms as a parameter. The transforms may use the
+    transformer like a dictionary for storing values and retrieving
+    values left by previous transforms.
+    As a naming convention each transform should use its class name
+    as a prefix for storing values in the dictionary.
