Views (or, to be more precise, view definitions) are located inside /presenter/views/ directory, within subdirectories
grouped by part of speech. If there is only one view for a part of speech, there will be a single file that defines a view.
Some parts of speech, such as verbs, could have multiple views. In this case in the verbs subdirectory there will
be multiple files; each file will define a separate view.
View files define view options. Those options are used to create a View object and build an inflection table.
All views share the same template parts that are stored in /presenter/templates directory. CSS file(s) are stored
in /presenter/styles.
View options define the following:
id: a view id is used in an HTML selector and other places where a view should be uniquely identified.name: a view name that will appear in an HTML view selector.title: a title that will be shown within a generated view representation.groupingFeatures: defines an order of grouping features that will be used to build a view tree. This sets how a view table will be structured into rows and columns.
