This plugin integrates live foreign exchange rates into a website, primarily for site owners or developers who need to display current currency values. It fetches data from an external API and provides multiple methods for displaying this information to visitors.

• Shortcode Integration: Insert a customizable currency converter anywhere on a site using a simple shortcode, allowing visitors to check and calculate between selected currencies.
• Widget Display: Add a currency rates widget to sidebars or other widget-ready areas, with configurable options for which currencies to show.
• Automatic Post Display: Configure the plugin to automatically display relevant exchange rates at the bottom of specific posts based on categories, tags, and publication date.
• Scheduled Updates: Rates are updated automatically once per day using a scheduled task, ensuring the displayed information remains current without manual intervention.
• Local Data Storage: Fetched rate data is saved locally as a JSON file, reducing API calls and improving load times for widget and post displays after the initial update.
