SUGGESTION: Function tree instances

Had some discussions on how function-tree can be a bit friendlier about creating more instances, typically for server side usage.

The API change would be:

const FunctionTree = require('function-tree')

const myFunctionTree = new FunctionTree({
  // Add directly to context (ContextProvider)
},
[
 // Providers
])

// Global listeners
myFunctionTree.on('EVENT', () => {})

const run = myFunctionTree([
  // Some tree definition
])

// Specific tree listeners
run.on('EVENT', () => {})

// Run tree, returns a promise
run({foo: 'bar'})
  .then(() => {})
  .catch(() => {})

@christianalfoni got it. will be experimenting with tree in tree this week and let you know how it goes. I think that especially in node environments this could be quite handy.

Yes, exactly 😃 Basically you kinda bind a tree to an execution allowing you to listen to events for only that specific tree execution, instead of only globally like it does now.

Also returning a promise allows you to use this as middleware for example 😃
