Statistics, adjustment methods and step-by-step demonstration

[PeturOA]

• Display adjustment seat allocation sequence on webpage as well as in excel output (Single election only)
• Provide allocation sequence for more adjustment methods than just Icelandic law and Monge
• Fix errors in some adjustment methods that were revealed when allocation sequence was examined
• • In particular, relative superiority was not being implemented correctly
• Add also a simpler version of RSA for comparison
• Add statistics for simulation
• • Calculate Skewness and Kurtosis
