How To Give A Function a Parameter in Fusetool

project is already pushed to github example

• this is no true function with parameter for now
• one way is use Callback and Handler
• if without each or not a list, the arg will be like and get all vars as arg
• if in an each and the var is a list, will give the elements in list
• use arg.data to get the value
• if the var is Observable, then use args.data.variableName.value
• in fact, the handler give both data and sender info
