/**
 * This sample demonstrates how to use the ImportCertificate function in the Amazon Certificate Manager 
 * service.
 *
 * Input parameters:
 *   Accesskey - Amazon access key
 *   SecretKey - Amazon secret key
 *   CertificateArn - Use to reimport a certificate (not included in this example).
 *   region - Amazon region
 *   Certificate - PEM file that contains the certificate to import. Ex: /data/certs/servercert.pem
 *   CertificateChain - The certificate chain, not including the end-entity certificate.
 *   PrivateKey - The private key that matches the public key in the certificate.
 *
 * Output parameter:
 *   CertificcateArn - The ARN of the imported certificate.
