     Function:  files = spp_file_retrieve(PATHNAME)
     Purpose:  Retrieve or Download Solar Probe data files (i.e. L0 files)  (Can be used to generate filenames too)
     INPUT:
     PATHNAME:  string specifying relative path to files.         Default might change-  Currently:  'psp/pfp/l0/YYYY/MM/mvn_pfp_all_l0_YYYYMMDD_v???.dat'
             PATHNAME must be relative to the LOCAL_DATA_DIR and REMOTE_DATA_DIR fields of the source keyword.
             "globbed" filenames (*,?) are accepted.
     typical usage:
       files = spp_file_retrieve('psp/xxxxxx/YYYY/MM/mvn_pfp_all_l0_YYYYMMDD_v???.dat',/daily_names)   ; get L0 files for user defined time span
       files = spp_file_retrieve(pathname,/daily_names,trange=trange)  ; set time range
    Keywords:  (All are optional - none are recommended)
     L0:   set to 1 to return PFP L0 files
     DAILY_NAMES : resolution (in days) for generating file names.
             YYYY, yy, MM, DD,  hh,  mm, ss, .f, DOY, DOW, TDIFF are special characters that will be substituted with the appropriate date/time field
             Be especially careful of extensions that begin with '.f' since these will be translated into a fractional second.
             See "time_string"  TFORMAT keyword for more info.
     TRANGE : two element vector containing start and end times (UNIX_TIME or UT string).  if not present then timerange() is called to obtain the limits.
     SOURCE:  alternate file source.   Default is whatever is return by the function:  mvn_file_source()    (see "mvn_file_source" for more info)
     FILES:  if provided these will be passed through as output.
     VALID_ONLY:  Set to 1 to prevent non existent files from being returned.
     CREATE_DIR:  Generates a filename and creates the directories needed to create the file without errors.  Will not check for file on remote server.

     KEYWORDS Passed on to "FILE_RETRIEVE":
     LAST_VERSION : [0,1]  if set then only the last matching file is returned.  (Default is defined by source)
     VALID_ONLY:  [0,1]   If set then only existing files are returned.  (Default is defined by source keyword)
     VERBOSE:  set verbosity level (2 is typical)
     USER_PASS:  user:password combination for the remote server
     LIMITATIONS:
       Beware of file pathnames that include the character sequences:  YY,  MM, DD, hh, mm, ss, .f  since these can be retranslated to the time
