Using variables as parameters of a task.

[JustusPan]

Currently BTree node should must be set as a child of a node with script. I hope we can assign any accessible variables in that script to the parameters list of a task node in BTEditor.

the variable of that script is always accessible hence the function and variable in the same script. i will not changed the pattern for the btree must have a parent to control with.
