    3333 * Reducing multiple calls to data files. On testing the Grid Series Feature API it was apparent that many files were being re-opened a number of times to fetch metadata or axis information. This repeated I/O should be reduced. One method might be to read in all coordinate variable values when scanning and store these inline. This shouldn't be a massive bulk because most datasets will only need to reference a few domains that are repeated for different variables (phenomena).

     35 * Typecode - a service sitting on top of CSML will get requests for data. It will have to estimate the cost (size, duration) of a request. It therefore needs to know the typecode of the data arrays. If they are short integers the output will be a lot smaller than an array full of doubles. It would be useful to put typecode into CSML.
