pavel:
  run avm with web-marine in dashboard(or something other big)
  think about problems arised
  design interface for loading services in fluence-js

valery:
  add interaces needed by pavel:
    - provide names of exported functions
    - add interface for calling wasm IT functions : func call(module_name, func_name, argsInJson)
    -
