add pdf file to test findText() search across lines
This pdf test file was chosen (from a google search) because:
- it has diacritics (spanish accents)
- it's produced by latex and uses hyphenation to split words across lines.
- it uses the Creative Commons license CC BY-NC-SA 4.0, as shown on second page of the original file --> http://oa.upm.es/37137/1/PFC_JEREZ_GUERERO_JOSE_LUIS.pdf , which is the first page of our two-page extract from the original file we use as test file.
