extract or plot (on console or to pdf) deviance change from ConQuest logfile

1	plotDevianceChange ( path , plot = TRUE , pdf = FALSE , out.path = NULL , extreme.crit = 0.75 )

`path`	full path to or connection of ConQuest logfile, or just a path (in which ConQuest logfiles are to be (recursively) searched for)
`plot`	if `TRUE` deviance change plot is created
`pdf`	if `TRUE` plot ist written to pdf
`out.path`	path for pdf output file
`extreme.crit`	numeric, threshold criterion to remove outliers, is multiplied with standard deviation of deviance change

ConQuest tends to not completely write out log if running and option 'update = yes' is used. To avoid warnings and malfunction manually delete the last potentially incomplete iteration from logfile. Points below 0 are red; if model converged ( see link{isConverged} for details ), the last point is larger and green

depends on plot and pdf; if both are FALSE the deviance change data is returned, this is a named vector with names = iteration number and values = deviance change from previous iteration; if more than one ConQuest logfile is processed a list of named vectors is returned
