[netCDF #FBR-789563]: netCDF examples problem

Hi Mariana,

In order to use the C++ software, it's first necessary to get, build, and 
install
the netCDF C software on which it depends.  Once that is installed, it's 
possible
to build install and use the separate netCDF C++ library.

Instructions for getting and building the netCDF C software are here:

  http://www.unidata.ucar.edu/netcdf/docs/
  http://www.unidata.ucar.edu/netcdf/docs/building.html

It looks like we should include a new link on building and installing the C++ 
library.
It's not as widely used as the C or Fortran libraries and it's installation 
documentation
has been neglected during our transition to a different documentation system 
(doxygen).

For now there's this:

  
http://www.unidata.ucar.edu/mailing_lists/archives/netcdfgroup/2011/msg00365.html

and the generic instructions you get by running

  ./configure --help

from the top level of the netcdf-cxx source directory, that tell you what 
environment
variables to set before you run

  ./configure
  make check
  make install
