  REGIONPROPS_CIRCULARITY - Calculates circularity of regions of interests

    NEWSTATS = REGIONPROPS_CIRCULARITY(STATS)

    Calculates circularity for regions of interest that have been
    returned by the IMAGES toolbox routines BWLABEL, BWBOUNDARIES, etc.

    STATS must be a structure of stats returned by the function
    REGIONPROPS that includes that parameters 'Area' and 
    'Perimeter' (see 'help regionprops').

    NEWSTATS is a structure that has all of the fields of STATS plus the
    additional field 'Circularity'.

    Circularity is defined as 4*pi(area/perimeter^2)
