[issue, #32] Definition einer sinnvollen JSON-Konfiguration mit konkreten Beispielen

   - Added JSON Structure for Test data from #27
   - Added README to explain how the structure works
   - Used CSS_SELECTOR as part of the ways to find data

data/configs/README.md

+# JSON Configurations
+
+There are two types of data to be processed:
+
+1. Word files ending with `.docx`
+2. FAQ Websites:
+    1. Websites with Questions and Answers as Text in the same page
+    2. Websites with Questions as texts in the same page, and a link to the Answer on a separate page
+    
+### `.docx` JSON structure
+```
+{
+    "type": "doc",  # type either "doc" or "url"
+    "name": "htc_sync_manager_faq.docx", "name of the file with its extension"
+    "question" : {
+        "style": "normal", # value "normal", "heading1", "heading2" etc.
+        "format": "bold",  # the format of the text "italic", "bold" "strikethrough" etc.
+        "size": 12         # font size
+    }
+}
+```
+
+### Websites with Question-Answer on same page
+```
+{
+  "type": "url",    # type either "doc" or "url"
+  "name": "https://www.berlin.de/sen/finanzen/steuern/informationen-fuer-steuerzahler-/faq-steuern/artikel.697552.php", # URI of the website
+  "question" : {
+    "type": "text", # "text" indicates its html on the same site
+    "css_selector": "div.block a" # css selector to the question, you can check it using the webconsole document.querySelector(css_selector)
+  },
+  "answer":  {
+    "type": "text", # same as above
+    "css_selector": "div.block .text" # same as above
+  }
+}
+```
+
+### Websites with Question on the same page, answer on a separate page
+```
+{
+  "type": "url", # same as above
+  "name": "https://www.stvo.de/info/faq", # same as above
+  "question" : {
+    "type": "text", # same as above
+    "css_selector": "table.category > tbody  td.list-title > a", # same as above
+  },
+  "answer":  {
+    "type": "href", # link to answer found in the href attribute of the href_css_selector
+    "href_css_selector": "table.category > tbody  td.list-title > a", # path to the link, found in the href attribute of the object if selected using document.querySelector(href_css_selector)
+    "css_selector": "div.item-page > div:nth-child(5)" # where to find the text data of the answer on the new page
+  }
+}
+```
+
+
+### Notice
+Of the 5 sites listed under `test-data/PSE 5 Websiten.txt`, the url `https://de-de.facebook.com/business/faq/` has no config json
+as facebook doesn't have static html to parse and the content is dynamic so it makes parsing using only html not possible.
