This interface represents a class that transforms a Block tree in some way.
The transform may be initialized with some parameters that control the operation
of the transform. These parameters have been already tokenized by space delimiters
and supplied in the
initialize(StringTokenizer) method call.
When it is time to transform an existing Block tree (or subtree) or set of Block
properties, the BlockTransform instance is supplied a
object which contains the necessary context to carry out the transformation.
