Ward Fisher 1e9f243f85 Fixed netcdf-c issue #30 (on github) related to cmake-generated nc-config script. 
Initial split of Guide from rest of documentation.  Using 'tagfiles' to cross-reference from one documentation set to the other works, but then it drags all of the 'external' related pages into the index of the other.

Modified visability of the external groups and pages.

Adding proper section names to 'Example' sections, to avoid Doxygen warnings.

Initial split of Guide from rest of documentation.  Using 'tagfiles' to cross-reference from one documentation set to the other works, but then it drags all of the 'external' related pages into the index of the other.

Modified visability of the external groups and pages.

Adding proper section names to 'Example' sections, to avoid Doxygen warnings.

Reorganizing documentation into two separate doxygen projects.

Moved .texi documents into an old directory.

Pulled the tutorial document into a separate document, similar to the guide document.

/** \ingroup user_types
Create a compound type. Provide an ncid, a name, and a total size (in
bytes) of one element of the completed compound type.
After calling this function, fill out the type with repeated calls to
nc_insert_compound(). Call nc_insert_compound() once for each field
you wish to insert into the compound type.
\param ncid \ref ncid
\param size The size, in bytes, of the compound type.
\param name \ref object_name of the created type.
\param typeidp The type ID of the new type is copied here.
\returns ::NC_NOERR No error.
\returns ::NC_EBADID Bad \ref ncid.
\returns ::NC_EBADTYPE Bad type id.
\returns ::NC_ENAMEINUSE That name is in use.
\returns ::NC_EMAXNAME Name exceeds max length NC_MAX_NAME.
\returns ::NC_EBADNAME Name contains illegal characters.
\returns ::NC_ESTRICTNC3 Attempting a netCDF-4 operation on a netCDF-3 file.
\returns ::NC_ENOTNC4 This file was created with the strict netcdf-3 flag, therefore netcdf-4 operations are not allowed. (see nc_open).
\returns ::NC_EHDFERR An error was reported by the HDF5 layer.
\returns ::NC_EPERM Attempt to write to a read-only file.
\returns ::NC_ENOTINDEFINE Not in define mode.
