====/igg/bookings====
Retrieve a list of all bookings of a golfer. Bookings with a startdate that is already behind us are ignored.

parameters:
|auth	|the authorisation code you received from Intogolf BV (mandatory)|
|relnr	|client id of the use|
|relkey |the hash key that was provided upon login (mandatory)|
|crsnr	|limit the results to only this course|
|lng	|1 english 2 dutch (default if parameter is omitted)|

example: https://backend.ikgagolfen.nl/igg/bookings?auth=<your authorisation code>&relnr=398801&relkey=68de29c0547a5c23ad51f62154d1177c

result:
<code>{
  "bookings": [
    {
      "crsnr": 5,
      "crsphone": "020-6361010",
      "startdate": "20120928",
      "starttime": 640,
      "reftype": 1,
      "refnr": 3054643,
      "descr": "teetime on a`dam waterland, 2 golfers, 9h.",
      "candeleteyn": 1
    }
  ]
}</code>

If candeleteyn = 0, you need to disable the delete function and display a message that the user will have to call the golfcourse (at crsphone) in order to delete the booking

reftype can be one of the following:
|1 |teetime reservation|
|2 |golf lesson|
|3 |subscription for a golf competition|

refnr is the internal id of the booking

if a wrong authorisation code is provided, the backend will return “no authorisation”
