Summary: MDSIO output redriection

Initial Comment:
A feature is needed that provides more flexibility in 
controlling path names for I/O. In particular

 ECCO uses temporary subdirectories for adjoint time 
history files.

 Helen needs to be able to cycle over duplicate I/O 
roots for large inout datasets to provide high-speed 
I/O.

 For high frequency I/O (such as used for generating 
offline fields) it is useful to be able to put I/O 
into different directories based on iteration number.

 Two thoughts on possible general purpose 
implementations are 

 1. stuff using links in pre run scripts (yuck)

 2. enhance mdsio to include an output redirection 
mechanism that means that mdsio file opens will 
redirect output based on pattern matching rules. For 
example a rule that says files of name "adj*" go to a 
certain directory pathname could be specified. The 
rules could be specified in a "data.mdsio" input file 
containing "pattern pathname" pairs. The C regexp 
parser could be called to determine matches (maybe??).

 Otherwise a less general solution could be done for 
now.
