/**
* Set a cascade configuration array.
*
* Each value in the array is the maximum number of entries that node can
* have before it is being collapsed. The last value is repeated for all
* further levels.
*
* Example:
* array(10,5,0) - Nodes from the first level are expanded if they have less
* than or equal to 10 child nodes. Nodes from the second level are ex-
* panded if they have less or equal to 5 nodes and all lower levels
* are collapsed.
*
* Note:
* To reset, simply call this function with no arguments.
