String removeAdditionalRanges(String line, ArrayList indices, ArrayList newRanges)
Removes ranges of characters from a line and adds their indices to an ArrayList.

int offset = 0;
for (int i = 0; i < newRanges.size(); i++) {
 line = line.substring(0, newRanges.get(i)[0]) + line.substring(newRanges.get(i)[1] + 1);
 while (indices.get(offset) <= newRanges.get(i)[0] + offset)
 offset++;
 int insideOffset = 0;
 while (offset + insideOffset < indices.size()
 && indices.get(offset + insideOffset) <= newRanges.get(i)[1] + offset + insideOffset)

boolean removeByReference(ArrayList list, T object)

 list.remove(i);
 return true;

 char c = buffer.charAt(i);
 if (c == ')')
 inParentheses = false;
