%{html: "<div class='exdiff-eq'>ab</div><div class='exdiff-ins'>c</div><div class='exdiff-eq'>d</div>", length: 1}

> Exdiff.diff("abd", "abcd", wrapper_tag: "span")
%{html: "<span class='exdiff-eq'>ab</span><span class='exdiff-ins'>c</span><span class='exdiff-eq'>d</span>", length: 1}

> Exdiff.diff_to_html("abd", "abcd")
{1, "<div class='exdiff-eq'>ab</div><div class='exdiff-ins'>c</div><div class='exdiff-eq'>d</div>"}

> Exdiff.diff_to_html("abd", "abcd", wrapper_tag: "span")
{1, "<span class='exdiff-eq'>ab</span><span class='exdiff-ins'>c</span><span class='exdiff-eq'>d</span>"}
```
