/**
* Defines a {@link org.apache.isis.core.commons.components.Component}
* architecture, along with factories (called {@link org.apache.isis.core.commons.components.Installer}s)
* to install (or create) those components.
*
* <p>
* There are three subinterfaces of
* {@link org.apache.isis.core.commons.components.Component}, for three different
* scopes:
* <ul>
* <li><p> {@link org.apache.isis.core.commons.components.ApplicationScopedComponent application-scoped} </p></li>
* <li><p> {@link org.apache.isis.core.commons.components.SessionScopedComponent session-scoped} </p></li>
* <li><p> {@link org.apache.isis.core.commons.components.TransactionScopedComponent transaction-scoped} </p></li>
* </ul>
*
* <p>
* Many {@link org.apache.isis.core.commons.components.Component}s may also be injectable,
* meaning that they know hot to inject themselves to a candidate object "if appropriate".
* The convention adopted in most cases is for an object requiring injection of
* component <tt>Xxx</tt> to implement an <tt>XxxAware</tt> interface that
* defines a <tt>setXxx(Xxx)</tt> method.
