emonk_helper

Some emonk extensions to ease its usage in applications.

For now it provides an emonk contexts pool management. Each emonk context is a thread so you have to reduce their number.

The pool allows simple javascript call in a context and multiple javascriptcall to a context.

Requirements

1. Latest emonk.
2. R14A or superior.
