/**
 * Overall application container.
 *
 * @extends React.Component
 *
 * @property {ReactNode} children - Overall application component.
 * Usually, a router or nested providers.
 *
 * @property {SchemaType} mapping - Mapping for UI Kitten components.
 * This is designed to be provided from any `@eva-design/*` package.
 * If provided, will be merged with *customMapping* and compiled into styles during the runtime.
 * Can be improved with build-time processing with `@wirthus/ui-kitten-metro-config` package.
 *
 * @property {CustomSchemaType} customMapping - Customized mapping.
 *
 * @property {ThemeType} theme - Current theme.
 * Designed to be provided from any `@eva-design/*` package.
 *
 * @property {ThemeStyleType} styles - Styles compiled by bootstrapping Eva packages.
 * If provided, will replace runtime styles processing.
 * Usually, can be provided by `@wirthus/ui-kitten-metro-config` package.
 *
 * @overview-example Simple Usage
 * ApplicationProvider is designed to be the root component of the application.
 * It should be rendered **once**, to provide Eva styles for nested components.
 * ```
 * import React from 'react';
 * import { ApplicationProvider, Layout, Text } from '@wirthus/ui-kitten-components';
 * import * as eva from '@eva-design/eva';
 *
 * export default () => (
 *   <ApplicationProvider {...eva} theme={eva.light}> // <-- {eva.dark} for dark mode
 *     <Layout style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
 *       <Text>Welcome to UI Kitten</Text>
 *     </Layout>
 *   </ApplicationProvider>
 * );
 * ```
 *
 * @overview-example Ecosystem
 * Also, it may accept [custom themes](guides/branding) and [icon packages](guides/icon-packages)
 * to provide a highly customizable, design system based application.
 * ```
 * import React from 'react';
 * import { ApplicationProvider, IconRegistry, Layout, Text } from '@wirthus/ui-kitten-components';
 * import { EvaIconsPack } from '@wirthus/ui-kitten-eva-icons';
 * import * as eva from '@eva-design/eva';
 *
 * export default () => (
 *   <React.Fragment>
 *     <IconRegistry icons={EvaIconsPack} />
 *     <ApplicationProvider {...eva} theme={{ ...eva.light, ...myTheme }}>
 *       <Layout style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
 *         <Text>Welcome to UI Kitten</Text>
 *       </Layout>
 *     </ApplicationProvider>
 *   </React.Fragment>
 * );
 * ```
