Accessors to children

[Keith Hodges]

Lukas,

When PRChildren is empty, I am getting uneccessary database accesses at 
every leaf node. I am sure that there are several ways of solving this 
but for now I am experimenting in my image with...

PRStructure>>#childrenDecoration removed

and an access interface defined for children...

#addChild:
#childAt:
#childAt:ifAbsent:
#childAt:ifPresent:
#childrenIncludes:
#removeChild:

Such that if there are no children then no PRChildren decoration is 
added into the structure's decorations.

would this change be acceptable?

Keith
