Editing Engine:CCMD context (section)

== Examples ==
=== Default values ===
* Try to change to a non-existent context.
<kua>
> context bob
Unknown: bob
</kua>
* Called with no name. The current context is printed.
<kua>
> context
global
</kua>
=== Context separation ===
* Same as the first example. But change to the known 'client' context, which is addressable from the 'global' context. 
<kua>
> context client
</kua>
* Start the client service, and change the client 'bob' variable which exists only in the 'client' context.  
<kua>
> start
Client started.
> bob 8081
> bob
'bob' is '8081'
> context
client
</kua>
* Change back to the 'global' context. Test to see that the bob variable in 'client' is not in 'global'.
<kua>
> context global
> context
global
> bob
Unknown: bob
</kua>

=== Without switching ===
In these examples a context is addressed directly without using the context command.
* Show current context.
<kua>
> context
global
</kua>
* Start the client service directly from global without switching.  
<kua>
> client start
Client started.
</kua>
* Set the 'bob' variable in client, check its value in 'client', and verify it's not in 'global'. 
<kua>
> client bob 8081
> client bob
'bob' is '8081'
> bob
Unknown: bob
</kua>
