About the group feature

[m-narita-s-style]

Hello

Thank you for creating such a great tool.
I want to use this tool.

I've been running the tutorial for a while and noticed that the group feature doesn't work.

In fact, there does not appear to be a group attribute.

	type ClientGroup struct {
	Clients string `yaml:"clients,omitempty"` // uint
	Db string `yaml:"db,omitempty"`
	Iter string `yaml:"iter,omitempty"` // uint
	IterClients string `yaml:"iter-clients,omitempty"` // uint
	IterExecGroup string `yaml:"iter-exec-group,omitempty"` // uint
	Name string `yaml:"name,omitempty"`
	QPS string `yaml:"qps,omitempty"` // uint
	QPSClients string `yaml:"qps-clients,omitempty"` // uint
	QPSExecGroup string `yaml:"qps-exec-group,omitempty"` // uint
	Runtime string `yaml:"runtime,omitempty"`

	TPSClients string `yaml:"tps-clients,omitempty"`
	TPSExecGroup string `yaml:"tps-exec-group,omitempty"`
	Trx []string `yaml:"trx,omitempty"`
	}

Has this feature been implemented yet?
