Version 0.1-7 (2026-05-17)
  * NEW: relative reliability (O'Connor, 2018) 
  * NEW: plotPIccc returns the standard errors of all parameters 
         given they are provided by the originating package. 
         Otherwise, the respective list elements contain NAs.
  * NEW: Option 'empirical' provides for empirical CCCs and
         TCCs. Several options allow for fine-tuning.
  * NEW: Option type='ESC' for the empirical score function.
  * CHG: The classical PI-Map connects the parameters across 
         items. This allows for easier detection of threshold
         disordering.
   

Version 0.1-6 (2024-09-07)
 * NEW: Option 'legoff' (legend offset) for  
        vertical positioning of legend.
 * NEW: Options 'TIFmax' and 'SEmax' for individual 
        scaling of TIF and SE curves
 * CHG: Former option 'hidelab' renamed to 'showlab' 
        with reversed meaning and extended options:
        0 = no labels at all
        1 = show thetas at bottom of diagram
        2 = show item labels at left (y-)axis
        3 = show item function diagram labels
        4 = show y-axis labels of PP histogram
        5 = show y-axis labels of (s)SE line
        6 = show y-axis labels of (s)TIF line.
