/**
* Contains options supported in the {@code ComputeService#createNodesInGroup}
* operation.
* Usage
The recommended way to instantiate a TemplateOptions object is to
* statically import TemplateOptions.* and invoke a static creation method
* followed by any/all desired instance mutators.
*
*
* import static org.jclouds.compute.options.TemplateOptions.Builder.*;
*
* ComputeService client = // get connection
* templateBuilder.options(inboundPorts(22, 80, 8080, 443));
* Set set = client.createNodesInGroup(tag, 2, templateBuilder.build());
*
*
* Note that options can only be assigned to a builder once, so if assigning e.g. inboundPorts and tags,
* that must be done in with mutators in a single call to options --
* templateBuilder.options(inboundPorts(22, 80, 8080, 443).tags("I love it!"))
* -- not as repeated calls to options.
