/**
* This method finds and returns all the strings found in the graph used to give a variable its
* value. Each found string will be splitted with comma and the results will be treated as unique
* values. For example In graph: reqtag1 = "REQ1" + ",REQ2," reqtag1 = reqtag1 + "REQ3" reqtag2 =
* "REQ3,REQ4" reqtag3 = "RE" + "Q5," reqtag4 = getValueFromExternalFunction("REQ6");
*
* @return Hashmap with the variable name as key, and a string containing 1 to many colon
* separated values, as the value For example In HashMap ({key,value} {
* reqtag1,"REQ1:REQ2:REQ3" reqtag2,"REQ3:REQ4" reqtag3,"RE:Q5" reqtag4,"REQ6"
