netcdf4.0 alpha passes nco regression tests & benchmarks

Hi Ed & James

Consider it a single data point, but one that represents a number of tests, 
including compiling with both opendap and nco, and testing nco via both local 
files and opendap-mediated access.

Altho I haven't yet run it thru valgrind, it looks like it links with nco and 
opendap much like the 3.6 series and seems to have the same functionality. It 
does not seem to have any explosive memory leaks ;).

The netcdf4.0-linked code passes all the local file benchmarks equally as well 
as the code linked to netcdf 3.6.0 and works at least as well on the 
OpenDAP-retrieved data.  BY that, I'm testing it vs a system equally remote 
to the DAP server (the server is linked against the netcdf 3.6 lib), but with 
code built with the netcdf 3.6 libs.  

Neither works perfectly (seemingly due to latency and timeout issues - still 
have to debug this.  If the nco benchmark code is run on the same machine as 
the server, it runs to completion just fine, if slower than accessing the 
local files, as you might guess), but the netcdf4.0-linked code gets further 
thru the benchmarks.

FYI...
