title: Add header to csv before converting to shapefile
body: <p>I have a code that converts csv files to shapefiles, but because my csv files do not have a header, the first line of data is replaced by the header in shp.writer. How can I add a header to the csv file before it is written as a shapefile?</p>
  
  <pre><code>import glob
  import csv
  import shapefile as shp
  #lon, lat, count = [],[],[]
  for filename in glob.glob('/data/kbrown/GLM/plots/test/hold/*.csv'):
      revFilename = 
      filename.replace('/data/kbrown/GLM/plots/test/hold/*.csv',"")
      rev2Filename = revFilename.replace(".csv","")
      out_file = rev2Filename + '_temp.shp'
      print(out_file)
  
      with open(rev2Filename + '.csv') as f:
  #    writer = csv.DictWriter(f, fieldnames = ["Lat", "Lon", "Count"], delimiter = ";")
  #    writer.writeheader()
      next(f)
      r = csv.reader(f, delimiter=',')
      lon, lat, count = [],[],[]
      for row in r:
          lon.append(float(row[0]))
          lat.append(float(row[1]))
          count.append(int(row[2]))
  #            f.close()
  #        print(lon)
      w = shp.Writer(shapeType=shp.POINT)
  #    w.autoBalance = 1
      w.field('lon', "F",10,10)
      w.field('lat',"F",10,10)
      w.field('count',"N",10)
      w.autoBalance = 1
      for j,k in enumerate(lat):
          w.point(lon[j],lat[j])
          w.record(lon[j], lat[j], count[j])
      w.save(out_file)
      w.shp.close()
      w.shx.close()
      w.dbf.close()

  <p>As you can see, the first line of data is deleted, and replaced by the header. How can I fix this? Any help would be appreciated.</p>
