Tests search_excerpt() with several simulated search keywords.

Passes keywords and a sample marked up string, "The quick brown fox jumps over the lazy dog", and compares it to the correctly marked up string. The correctly marked up string contains either highlighted keywords or the original marked up string if no keywords matched the string.

Tests the search_excerpt() function.

  // important for HTML formatting. Remove these for comparison.
