* <p>A general container for xchain commands. Children of a chain are executed, in order, until one of them

* <p>If one of the chain's children returns <code>true</code>, then each child that was executed will have its post process
* executed and then the chain will return <code>true</code>.</p>
* <p>If one of the chain's children throws an exception, then each children that was executed, including the
* command that threw the exception, will have its post process executed with the exception that was thrown.
* If none of the children's post process returns <code>true</code>, then the exception will be rethrown by this chain.
* If any of the childrens post process returns <code>true</code>, then this chain will return <code>false</code> and its next
* sibling will execute.</p>
