Renamed configSDM.xml to config.xml
Reverted the influence separation in edges (value + type) due to problems when dealing with percentage.
Fixed the problems when changed from boolean to string for collapsefunction and edgestroke in config.xsd in config.java, edge.java and variables.java
Made a minor change how the Average function works in variables.java.
Refactored ColorSchemes names
Changed how trafic-light color is calculated, by using min and max values instead of thresholds.
Refactored Config.java (edgetype, edgestroke, edgecollapse into a single variable type EdgeType) for easier understanding. All codes that used these variables were changed as well.
Changed in Variables.java the functions that calculated MAX value. Now the same function calculate MAX, MIN and AVERAGE values for each edge type.
Refactored config.xsd and config.xml
Added a new element "attribute" in input.xsd
