===============
Updated simple Elixir/Erlang C Nodes example. The server `cnode_ei_s2.c` has been updated to utilize the `ei_***` api.
0. Test Elixir C Node server
```shell
shell1$ ./cserver_ei3 3456
Connected to e1@127.0.0.1
message: 1
erl_reg_send: msgtype: 6 buff: 0x7fd4ec500010 idx: 42 bufsz: 128
term: ``
bar: 4
tick: 0
```
```shell
shell2$ erl -name e1 -setcookie secretcookie
Erlang/OTP 22 [erts-10.6.1] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe]
Interactive Elixir (1.9.4) - press Ctrl+C to exit (type h() ENTER for help)
iex(e1@127.0.0.1)1> Node.connect :'cnode@127.0.0.1'
true
iex(e1@127.0.0.1)2> Complex4.bar(4)
4
iex(e1@127.0.0.1)3>
```
1. Test C node server example with short node names
```shell
$ ./cserver 3456
$ erl -sname e1 -setcookie secretcookie
Erlang/OTP 17 [erts-6.1] [source] [smp:2:2] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V6.1 (abort with ^G)
(e1@alpha)1> c(complex3).
{ok,complex3}
(e1@alpha)2> complex3:foo(3).
4
(e1@alpha)3> complex3:bar(5).
10
```
2. Test C node server example with long node names
```shell
$ ./cserver2 3456
$ erl -name e1 -setcookie secretcookie
Erlang/OTP 17 [erts-6.1] [source] [smp:2:2] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V6.1 (abort with ^G)
(e1@alpha.example.com)1> c(complex4).
{ok,complex4}
(e1@alpha.example.com)2> complex4:foo(3).
4
(e1@alpha.example.com)3> complex4:bar(5).
10
```
3. Test C node client example
```shell
$ erl -sname e1 -setcookie secretcookie
Erlang/OTP 17 [erts-6.1] [source] [smp:2:2] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V6.1 (abort with ^G)
(e1@alpha)1> c(complex3).
{ok,complex3}
```
run the C node client
```shell
$ ./cclient
```
back to the erlang shell
```shell
(e1@alpha)2> complex3:foo(3).
4
(e1@alpha)3> complex3:bar(5).
10
```
