Issue:
Having several start-end tags in included page
Having several start-end tags in included page, results in including only the first appearance.

Is it possible to have more than one section included?

```markdown
<!--start-tag-->
## Important Content1
<!--end-tag-->

[unimportant content]

<!--start-tag-->
## Important Content2
<!--end-tag-->

```

Pull request:
Allow to include from different parts of the same page
Using the same `start` and `end` arguments, allow to include multiple times from the same page. Closes #50
