/**
* Handles a content request to view a node children list
* Requests :
* - GET /api/v1/content/node/<nodeId>/list(/offset/<offset>/limit/<limit>/sort/<sortKey>/<sortType>)
* - Every parameters in parenthesis are optional. However, to have offset/limit and sort, the order is mandatory
* (you can't provide sorting params before limit params). This is due to a limitation in the regexp route.
* - Following requests are valid :
* - /api/ezp/content/node/2/list/sort/name => will display 10 (default limit) children of node 2, sorted by ascending name
* - /api/ezp/content/node/2/list/limit/50/sort/published/desc => will display 50 children of node 2, sorted by descending publishing date
* - /api/ezp/content/node/2/list/offset/100/limit/50/sort/published/desc => will display 50 children of node 2 starting from offset 100, sorted by descending publishing date
*
* Default values :
* - offset : 0
* - limit : 10
* - sortType : asc
