[saga-rg] AlreadyExists

[sbrandt at cct.lsu.edu]

I'm new to the Saga list and have started to look over the java code  
and various docs.

I'm wondering if the exception AlreadyExists might be eliminated from  
the SAGA spec, in favor of different behavior -- namely to do nothing  
in the case where AlreadyExists would normally be thrown. This should  
be reasonable for mkdir(), adding a context, etc.

I believe this would be simpler and nicer for users.

Cheers,
Steve
