/**
* This method initiates and populates the hashmap reqs, with all requirements in the graph. There
* are two types of requirements: Ordinary and Variable. All of them are fetched by calling
* getReqTagKey for all the edges and vertexes in the graph The Ordinary requirements are directly
* put into the reqs hashmap. The Variable requirements are used as a lookup in the list of all
* the variable values returned by getAllVariableValues and the value matching the the Variable
* requirement are splitted with colon and put as keys into the reqs hashmap. The value for each
* entity in the reqs hashmap will be set to null, since no requirement are tested yet. Its never
* needed to call this method more than once.
