Extreme value search among one attribute and multiple nodes

[holgerteichgraeber]

Define an extreme value based on an attribute (e.g. wind) and it finds the corresponding extreme value among all nodes.

Previously, only an attribute-node pair was allowed for extreme value identification (e.g. wind-dena72).
