using netCDF for storing data from realtime source

[John Caron]

Hi Maghnus:

The point obs file format was designed for this problem:

The idea is to use the record dimension to append data as it comes in, which is much more efficient. 

However, different sampling rates are a problem not explicitly dealt with.
