Description
int 
strnatcasecmp ( string str1, string str2 )
     This function implements a comparison algorithm that orders
     alphanumeric strings in the way a human being would.  The
     behaviour of this function is similar to
     strnatcmp(), except that the comparison is not
     case sensitive.  For more information see: Martin Pool's Natural Order String Comparison
     page.
    
     Similar to other string comparison functions, this one returns
     < 0 if str1 is less than
     str2; > 0 if
     str1 is greater than
     str2, and 0 if they are equal.
