aggregator example uses hardcoded 'examples' value instead of parameterized (examplesRoot) value in path

In the aggregator example, in the coordinator.xml, there are several paths like

<uri-template>${nameNode}/user/${coord:user()}/examples/input-data/rawLogs/${YEAR}/${MONTH}/${DAY}/${HOUR}/${MINUTE}</uri-template>

<uri-template>${nameNode}/user/${coord:user()}/examples/output-data/aggregator/aggregatedLogs/${YEAR}/${MONTH}/${DAY}/${HOUR}</uri-template>

<app-path>${nameNode}/user/${coord:user()}/examples/apps/aggregator</app-path>

In these paths, "/examples/" should be "/${examplesRoot}/".
