Clean Up: remove nSetIndents

The motivation of this clean up is:
- Use the precomputed indents for all paragraphs.
- Pass the indents as a part of setup paragraph since indents are a
  per-paragraph parameter.
- Remove the nSetIndents call from Builder.setIndents since indents will
  be overwritten in generate() function.
