Improve knowledge base storage format

[kmehant]

Currently its a file directory with nesting. We need to improve this and move this to another format. We should make it for users to add new information while also easy for serialising and using it within the tool. Some options are:

1. simple CSV file
2. YAML

Feel free to suggest more such formats.
