 * @name Email Composer
 * @premier email-composer
 * @description
 *
 * Requires Cordova plugin: cordova-plugin-email-composer. For more info, please see the [Email Composer plugin docs](https://github.com/hypery2k/cordova-email-plugin).
 *
 *
 * @usage
 * ```typescript
 * import { EmailComposer } from '@ionic-native/email-composer/ngx';
 *
 * constructor(private emailComposer: EmailComposer) { }
 *
 * ...
 *
 *
 * this.emailComposer.getClients().then((apps: []) => {
 *    // Returns an array of configured email clients for the device
 * });
 *
 * this.emailComposer.hasClient().then(app, (isValid: boolean) => {
 *  if (isValid) {
 *    // Now we know we have a valid email client configured
 *    // Not specifying an app will return true if at least one email client is configured
 *  }
 * });
 *
 * this.emailComposer.hasAccount().then((isValid: boolean) => {
 *  if (isValid) {
 *    // Now we know we have a valid email account configured
 *  }
 * });
 *
 * this.emailComposer.isAvailable().then(app, (available: boolean) => {
 *  if(available) {
 *    // Now we know we can send an email, calls hasClient and hasAccount
 *    // Not specifying an app will return true if at least one email client is configured
 *  }
 * });
 *
 * let email = {
 *   to: 'max@mustermann.de',
 *   cc: 'erika@mustermann.de',
 *   bcc: ['john@doe.com', 'jane@doe.com'],
 *   attachments: [
 *     'file://img/logo.png',

 *     'file://README.pdf'
 *   ],
 *   subject: 'Cordova Icons',
 *   body: 'How are you? Nice greetings from Leipzig',
 *   isHtml: true
 * }
 *
 * // Send a text message using default options

 * ```
 *
 * You can also assign aliases to email apps
 * ```ts
 * // add alias
 * this.email.addAlias('gmail', 'com.google.android.gm');
 *
 * // then use alias when sending email
 * this.email.open({
 *   app: 'gmail',
 *   ...
 * });
 * ```
