I-EPOS 0.0.2

• updated epos.properties: new format for arguments for complex cost function (see agent.planselection.PlanSelectionOptimizationFunctionCollection:98). This new format support complex cost functions with more than two arguments. See epos.propoerties for the information on the new format.
• updated Configuration.java: now supporting an array of arguments for complex cost functions.
• added tree visualizer: added tree visualizer which shows the local cost of the agents in the tree at the final iteration of each simulation (darker colours show higher local cost)
