/**
 * INSTRUCTIONS
 * 1. Replace `$module_id   = 2;` with the id of the module you want to import entries to
 * 2. Replace `$module_type = 'popup';`with the module type. Accepted values can be popup, slidein, embedded, social_sharing
 * 3. Upload your CSV file and insert the URL in this line:
 *    $csv_path    = '/PATH/TO/FILE/hustle-import.csv';
 * 4. Make sure you map each column correctly. This can be done in the following lines:
 *    `$csv_map 	 = array(
 *			'email',
 *			'first_name',
 *			'last_name',
 *		);`
  * With above mapping, the first column contains the email, the second the first name and the third contains the last name
