8Changes:
91.1.2 explicitly declares i in Get_Cookie with var
101.1.1 fixes a problem with Get_Cookie that did not correctly handle case
11where cookie is initialized but it has no "=" and thus no value, the
12Get_Cookie function generates a NULL exception. This was pointed out by olivier, thanks
131.1.0 fixes a problem with Get_Cookie that did not correctly handle
14cases where multiple cookies might test as the same, like: site1, site

71only the first 2 parameters are required, the cookie name, the cookie
72value. Cookie time is in milliseconds, so the below expires will make the
73number you pass in the Set_Cookie function call the number of days the cookie
74lasts, if you want it to be hours or minutes, just get rid of 24 and 60.

76Generally you don't need to worry about domain, path or secure for most applications
77so unless you need that, leave those parameters blank in the function call.
