    o Newly visible function 'rimpoly' for random point generation
    o Additional control over small bandwidth action in leave-one-out bandwidth selectors
    o Improved edge-correction calculations for brute force adaptive leave-one-out
    o Updated citation information and documentation corrections
    
    
NEW FUNCTIONS

    o rimpoly
    Random spatial point generation based on a pixel image, returned with a polygonal window
    o SLIK.adapt
    Simultaneous bandwidth selector for global and pilot bandwidth for adaptive density estimates based on likelihood cross-validation
   
    
SIGNIFICANT USER-VISIBLE CHANGES

    o LIK.density, LSCV.density
    New argument 'zero.action' to provide greater control over the behaviour of leave-one-out
    calculations at very small bandwidths.
