List data backend spec:
url = //url for request
params = [] //additional params passed to url, i.e. query, or group
the url must understand the following requests:
number of items:
url?params&n=1
> {items: N}
items sorted by key range X to Y:
url?params&s=key:asc|desc&r=X:Y
> {items: [{k0:v0, k1:v1...}, {k0:v0, k1:v1...}]}
Examples:
/json/find?l=all&s=title&f=all&q=&a=desc&p=id,title,director,date,cast.length
/json/find?r=0:100&l=all&s=title&f=all&q=&a=desc&p=id,title,director,date,cast.length
