* Create this object in each `main` file that uses the Communication stack. It

* is used to initialize all libraries (primarily OpenSSL) and to fix some
|
|
* issues also related to OpenSSL (handling of SIGPIPE).
|
|
*
|
|
* We define a struct to take advantage of RAII so that the proper cleanup
|
|
* is called after we are finished using the SSL connection.
|
|
*
|
|
* Description of OpenSSL init can be seen here:
|
|
* https://wiki.openssl.org/index.php/Library_Initialization
|
|

|
|
* NOTE: This object must be created **exactly** once.
