clean_cli is in programm command line parser using for repl.
Example
let cli = Cli::<()>::builder()
.command(CommandBuilder::with_name("cmd")
.use_value(ArgType::Bool)
.parameter(Parameter::with_name("bool")
.value_type(ArgType::Bool)
.alias("b")
.alias("bb")
)
.parameter(Parameter::with_name("int")
.value_type(ArgType::Int)
.alias("i")
.alias("ii")
)
.parameter(Parameter::with_name("float")
.value_type(ArgType::Float)
.alias("f")
.alias("ff")
)
.parameter(Parameter::with_name("string")
.value_type(ArgType::String)
.alias("s")
.alias("ss")
)
