Netcdf DAP Support: Round 2....

For those brave enough to try it, I am specifically looking for the following:

1. configuration failures
2. execution failures (e.g. seg faults)
   
3. inconsistencies with the libnc-dap implementation 
4. performance problems vis-a-vis the libnc-dap implementation.

An important note. This version has a logging facility that can sometimes give important information. To turn it on in, say, the sh shell use:

   OCLOGFILE="" ; export OCLOGFILE 

which will turn on logging and send it to stderr. Alternatively use

   OCLOGFILE="filename.log"; export OCLOGFILE 

to append log output to a file named filename.log (or whatever you choose). If you report and error, it can sometimes help if you send along
this logfile output.
