The main feature of our app will be a fast lookup of words. For this, we will store our definitions inside an SQLite database and use its full-text search feature.

For the most part, we'll be using types from the Java Standard library, except for the JDBC SQLite database driver (https://github.com/xerial/sqlite-jdbc) and the Jackson JSON deserializing library (https://github.com/FasterXML/jackson).

Since we want to provide a fast lookup of words, the UI can be kept simple. We'll have a search area where a user can enter a word they want to look up, and below that, we'll display the results inside a ListView.
