Detailed Description

Defines a LogWriter that generates a NetCDF table of values.

A list of variable names is supplied to the constructor. If any of these variables change their value in a computation cycle, then a record is added to the NetCDF file with the current value of every variable. The Timestamp for each record corresponds to the time of the start of the computation cycle in which any value changed.
