Constant _expression_ Language

The Constant _expression_ Language is a really just a way to specify constant strings as a type of _expression_.

Available as of Camel 1.5

Example usage

The setHeader element of the Spring DSL can utilize a constant _expression_ like:

<route>
  <from uri="seda:a"/>
  <setHeader headerName="theHeader">
    <constant>the value</constant>        
  </setHeader>
  <to uri="mock:b"/>     
</route>

in this case, the Message coming from the seda:a Endpoint will have 'theHeader' header set to the constant value 'the value'.
