Features

• Allows text input for annotation to be dynamically added.
• annotations to be loaded
• Tags only or Tags & Relations as an option instead of separate function
• Moving Annotation Mode Button to RShiny input
• Added testing for new features

Testing

• Added selenium test for updating the text being annotated

Notes
Selenium tests sometimes fail if while the tests are running:

• the mouse is moved over the window,
• the window is resized
• the server is too slow running the shiny app

Thanks again for the work on this.
Before I can work on merging this some things need to be fixed

• r cmd check needs to pass (I've enabled CI, so you can see where R CMD check gives errors)
• all elements / examples which were there should still work (e.g. running the first example of recogito in the README and at ?recogito already gives different results as the current package version
• put the different elements in different pull requests
  • factor out the changes regarding unit testing (If at all these will work on all the different CRAN platforms)
  • adding changes in the javascript / R options
• I think the following needs to be kept in mind in order not to let all function arguments explode
  • in tags we can just put a vector of tags in case of mode annotation and it can be a list of tags (for the relations and the entities) as in tags = c("location", "person") or tags = list(entity = c("location", "person"), relation = c("lives-in", "objectof"))
  • we can use 1 argument options instead of having the function arguments mode, refresh, annotationMode, document the options and handle these in the recogito function itself
