code: public String replaceFrom(CharSequence sequence, CharSequence replacement) {
          return replaceFrom(sequence, replacement, CountMethod.MIN_ELEMENTS, SpanCondition.SIMPLE);
      }
docs: Replace all matching spans in sequence by the replacement,
  counting by CountMethod.MIN_ELEMENTS using SpanCondition.SIMPLE.
  The code alternates spans; see the class doc for {@link UnicodeSetSpanner} for a note about boundary conditions.
  @param sequence
  charsequence to replace matching spans in.
  @param replacement
  replacement sequence. To delete, use ""
  @return modified string.
