Add docs for the examples package

This review is big because it contains examples for the whole project.
The big size is mainly due to the site.xml, logos and css files which
are repeatedly created, and more aciidoc files are needed. The pom.xml
files are changed properly.

+== Schema for Trigger Event Status
+
+The trigger event provides a status as `UP` or `DOWN`.
+To avoid tests for these strings in the logic, we defined an Avro schema for an enumeration.
+This does not impact the trigger system (it can still send the strings), but makes the task logic simpler.

+This is the logic for the establish state.
+It is the most complicated logic, since establishing a situation for a decision is the most important part of any policy.
+First, the policy describes what we find (the switch block), in terms of 8 normal situations and 1 extreme error case.
+
+If required, it creates local context information for the problem (if it is new) or updates it (if the problem still exists).
+It also calculates customer SLA downtime and checks for any SLA violations.
+Finally, it creates a situation object.

+== Logic: Policy Match State
+
+This is the logic for the match state.
+It is kept very simple.
+Beside taking the trigger event, it also creates a timestamp.
+This timestamp is later used for SLA and downtime calculations as well as for some performance information of the policy.

+== VPN SLA Policy
+
+The VPN SLA policy is designed as a MEDA policy.
+The first state (M = Match) takes the trigger event (a link up or down) and checks if this is a change to the known topology.
+The second state (E = Establish) takes all available information (trigger event, local context) and defines what situation we have.
+The third state (D = Decide) takes the situation and selects which algorithm is best to process it.
+This state can select between `none` (nothing to do), `solved` (a problem is solved now), `sla` (compare the current customer SLA situation and select one to impede), and `priority` (impede non-priority customers).
+The fourth and final state (A = Act) selects the right action for the taken decision and creates the response event sent to the orchestrator.
+
+We have added three more policies to set the local context: one for adding nodes, one for adding edges (links), and one for adding customers.
+These policies do not realize any action, they are only here for updating the local context.
+This mechanism is the fasted way to update local context, and it is independent of any context plugin.
+
+The policy uses data defined in Avro, so we have a number of Avro schema definitions.
