Issue #1986264: Set a display key when static caching results in ViewsHighchartsOptions::getFieldValues()

Issue #1674928: prepare for ajax options. Fix dot notation string names function, and add corollary function for getting a single option definition from a dot notation string

Issue #1674928: load settings form defaults from views_plugin_style options, rather than passing another param. Cleanup docs and todos. Add working example selected option to ViewsHighchartsOptionsPieBasic

Issue #1674928: load all options templates, and show with states. Ajax loading here is causing greif - but would be ideal so TODO

Issue #1674928: move logic from highcharts_views_plugin_style_highcharts::render() to separate methods: validateChartTemplate() and loadChartTemplate(). Also introduce getChartTemplateSettingsForm() and load template-specific settings forms. Still need to load this via ajax on select

Issue #1674928: Add allowed values methods and update pie basic class as an example. This works with a single multivalue Field API field with allowed values, such as field_tags

Issue #1674928: update API documentation. Follow proposed D8 callback signature pattern, but as applied to callback classes

Issue #1674928: Remove highcharts_views_get_view_result(), in favor of parsing in Highcharts options template classes. Update class names in hook_highcharts_views_charts().

Issue #1937874: Update Highcharts Views documentation to coordinate with D8 hook callback signature documentation issue #1250500

Issue #1674928: Add Highcharts options reference definition (scraped from documentation. @todo update this from their new documentation, but requires a different approach. See issue for reasoning). Add functions to create FAPI elements for Views UI

Issue #1674928: fix options override function where new override properties do not exist on the original object. Also handle current issue where empty Views form elements return empty strings (this will not be an issue when we change from loading all options form elements at once to ajax loading only desired option overrides)

Issue #1674928: new method for getting chart templates within the view. Support both callbacks and classes to be declared in implementations of hook_highcharts_views_charts(). Update API documentation and add examples of both

Issue #1674928: implement hook_highcharts_views_charts() to provide options template classes from highcharts.options.inc to Views

Ensure potential multiple instances of the same method string declared by hook_highcharts_methods_alter() run only once

Issue #1720058: add exporting plugin library definition, and conditional rendering based on variable. @todo there is no UI to set the variable yet

Issue #1466050: Register Highcharts theme JS as a library, and conditionally load from variable. @todo add UI to set variable

Use hook_library(). Convert chart container to a render array, making use of libraries and attachments, and pass through drupal_render(). Drop highcharts_settings() and highcharts_load_js() (since we can do all this with #attached js), and theme_highcharts_chart() (since modules can now alter the render array). Remove $ajax param from  highcharts_render() (since drupal_process_attached() will handle ensuring libraries are only loaded once). Other related module and documentation cleanup. Clean up example in README.
