default values

[Robert Brenstein]

I just looked at the issue of default values for fields in V2. The 
kernel doc is not consistent on that, so I am not sure whether it is 
already supported or is planned to be added soon.

When discussing SetBlank on page 46, there is no mention of default 
values. On page 59, the discussion of SetBlank mentions using default 
values, but on page 98 there is no mention of defaults again. 
Confusing.

Furthermore, SetBlank should allow me to either use or ignore 
defaults, me thinks. I can think of situations requiring one or the 
other. May be we should have SetDefaults to do what is described on 
page 59 and keep SetBlank as described on pages 46 and 98. Or add a 
parameter to SetBlank telling it whether to use defaults or not.

I can't say what the situation is for creating new fields. The doc 
mentions CreateField() method when discussing CreateTable on page 35 
but I can't find it anywhere else in that doc.
