#   usage for free-users:
#
#     $upload=new rapidphp;
#     $upload->sendfile("myfile.rar");
#
#
#   usage for premium-zone:
#
#     $upload=new rapidphp;
#     $upload->config("prem","username","password");
#     $upload->sendfile("myfile.zip");
#
#
#   usage for collector's zone:

#     $upload=new rapidphp;
#     $upload->config("col","username","password");
#     $upload->sendfile("myfile.tar.gz2");
#
#
#   you can upload several files if you want:
#
#     $upload=new rapidphp;
#     $upload->config("prem","username","password");
#     $upload->sendfile("myfile.part1.rar");
#     $upload->sendfile("myfile.part2.rar");
#     // and so on
#
#   sendfile() returns an array with data of the upload
#    [0]=Download-Link
#    [1]=Delete-Link
#    [2]=Size of the sent file in bytes
#    [3]=md5 hash (hex)
