/**
* capiCatGetLevelNode: Seeks through the category
* tree and returns the node on a specific level.
*
* Example:
*
* + Category A (15)
* |-+ News (16)
* | |- News A (17)
* + Category B (18)
* |-+ Internal (19)
*
* Given you are in the leaf "News A" (idcat 17),
* and you want to get out in which "main" tree you
* are, you can call the function like this:
*
* capi_cat_getlevelnode(17,1);
*
* The example would return "Category A" (idcat 15).
* If you specify an invalid level, the results are
* undefined.
*
* @param $int idcat The category number
* @param $minLevel int The level to extract
*
* @return int The category node on a specific level
