When specifying the resource path via `--resource-path` the template will be searched there since pandoc 2.9.2.1.
To fix the broken travis build (`Could not find data file templates/eisvogel.latex`) the
current working directory `.` is included in the resource path for pandoc to find the template again.
- The example demonstrates the use of the filter `pandoc-latex-environments` to create custom admonition boxes with the `awesomebox` package.
*pandoc-latex-environment* is a pandoc filter for adding LaTeX environement on specific HTML div tags.
- Added LaTeX package `awesomebox` to the `travis.yml` file
