/**
* Default {@code main(...)} if an application does not provide one.
*
* This simply constructs a default container, starts it and performs
* a default deployment. Typically only useful for barren WAR applications.
*
* If providing their own {@code main(...)}, then the following needs to be known:
*
*
* - Any usage of {@code java.util.logging} may only follow the initial constructor
* of {@code new Swarm()}.
* - While this object may appear to be thread-safe, it does rely on general
* static instances for some facilities. Therefore, it should not be instantiated
* several times concurrently.
* - It can be instantiated multiple times serially, as long as one instance
* is disposed before another is created and used. This limitation may be removed
* in a future version, if required.
*
*
* If using this class either directly or implicit as a {@code main(...)}, certain
* command-line facilities are available. If used directly, the user should pass the
* {@code String...args} from his own {@code main(...)} to the constructor of this
* class if these command-line facilities are desired.
*
* Many internal aspects of the runtime container may be configured using the Java
* APIs for various fractions, XML configuration files, YAML configuration files, and
* Java system properties.
*
* Configuration ordering works as follows: Fractions configured through an XML
* configuration file takes precedence over the same fraction configured through the
* Java API. YAML or system properties may override portions or attributes of fractions
* defined either way. A system property override binds more strongly than YAML configuration.
