Comment(by walter):

 1. Samples are now in separate small files in the pysamples subdirectory
 2. You load samples from the toolbar and the sample code is copied to the
 journal
 3. Clicking on a block will open the chooser to load python code from the
 journal
 4. Python code is loaded on a per-block basis
 5. No error message is shown if the code is not loaded (not sure this is
 the best behavior)
 6. Python code can be edited in either Pippy or the plain text editor,
 Edit.
 7. Currently, the code loaded into a block is not saved between sessions.
 I am not sure of the best way to do this. If I save the code directly in
 the block, then it represents a serious security risk when projects are
 shared. Maybe I will save the object ids of the associated python files
 and thus require that the python file be explicitly shared and loaded (and
 hopefully examined) before it is executed?
