ComplexOutput data as reference always generates a file named "input.csv", should be "output".

Description

When returning a ComplexOutput as Reference (output as_reference is True), the filename generated by the server (and used in the built URL) is always "input", eg "input.csv" for a "txt/csv" output, or "input.xml" for an "application/xml" output. This is misleading to users as this is actually the Output file.

After some digging through the sourcecode, I found where that name is set:

pywps/pywps/inout/basic.py

Lines 271 to 276 in d0bb978

    
           def _build_file_name(self, href=''): 
        
               """Return a file name for the local system.""" 
        
               url_path = urlparse(href).path or '' 
        
               file_name = os.path.basename(url_path).strip() or 'input' 
        
               (prefix, suffix) = os.path.splitext(file_name) 
        
               suffix = suffix or self.extension

It appears there is no way to set this name on the ComlexOutput object, or on the FileStorage object or on the DataHandler object.

Hello,

You can change the output name by storing output data into a file.
