// this example is one of the most simple classes
// if you want to have a command that just does 1 word. `/reload` for example, also only is one word
// normally these commands start from that one word and go from there,
// so in this case we would get `/helloWorld say` because we specified that the commandObject is `say`
//  (or in another command this could be `/A b c d e`)
// however, because there is only one possibility `say`, we can set hasOnlyOneGroupMember to true
// this to tell the system that we can skip selecting that bit because it will always be that anyway.
// so you are left with `/helloWorld` (in that other command this would be `/A c d e`)

// by default doing only the command name (with 0 other params) will automatically go to the help command
// however, we can turn that off if we don't want that by setting isZeroParameterCommand to true

// to make sure it all works you simply have to do `CommandTreeSystem.createCommand(HelloWorldCommand)`
//  (and make sure the CommandTreeSystem has been initialized )
