GiniIndex: Gini-Index
In Mthrun/ABCanalysis: Computed ABC Analysis

calculation of the Gini-Index from Data

1	GiniIndex(Data,p)

`Data`	vector[1:n] describes an array of data: n cases in rows of one variable
`p`	optional, an vector of values specifying where interpolation takes place, created by `seq` of package base

uses ABCcurve and Gini4ABC

`Gini`	gini index i.e. the integral over Area *200 -100 given in percent i.e in [0..100]
`p`	vector [1:k], cumulative population in percent
`ABC`	vector [1:k], cumulative high data in percent
`CleanedData`	vector [1:m], columnvector containing Data>=0 and zeros for all NA, NaN and negative values in Data(1:n)
