Hedera Vocabulary List Feature

[Tanvez]

Currently, an instructor can only select one vocabulary list at a time to retrieve lemmatized tokens from for a certain text, so we would like to be able to select multiple lists at a time and display all of the tokens from all selected lists.

We would also like to enhance the vocabulary list interface to organize vocabulary lists into groups (e.g. chapters of a book).

Acceptance criteria:

• On a lemmatized text page, select multiple vocabulary lists to display known and unknown terms.
• On the vocabulary list display page, organize vocabulary lists into groups.
• In the vocabulary list selection component, display the lists organized by the above groups.
