int [].public int[] compilePattern(String data)
 Translate the given String into a int []
 representing the pattern matchable by this class. 
 This function translates a String into an int array
 converting the special '*' and '\' characters. 
 Here is how the conversion algorithm works:
 
 When more than two '*' characters, not separated by another character,
 are found their value is considered as '**' (MATCH_PATH). 
 The array is always terminated by a special value (MATCH_END). 
 All MATCH* values are less than zero, while normal characters are equal
 or greater.
