Scrape AIS data

[dpwoert]

new issue because we can scrape AIS data with a trial account now (see: #90).

url

http://data.aishub.net/ws.php?username=A&format=B&output=C&compress=D&latmin=E&latmax=F&lonmin=G&lonmax=H

API options

1) A - your AISHub username. You will receive it after joining AISHub.
2) B - format of data values (0 - AIS encoding , 1 - Human readable format)
3) C - output format (xml, json)
4) D - compression (0 - no compression, 1 - ZIP, 2 - GZIP, 3 - BZIP2)
5) E - South (minimum) latitude (default = -90)
6) F - North (maximum) latitude (default = +90)
7) G - West (minimum) longitude (default = -180)
8) H - East (maximum) longitude (default = +180)

@Hedva, can you determine latmin, latmax, lonmin and latmax?
