"""Constructor.
NODE-NAME = string
The name for this node.
OPTS = <instance of ErlNodeOpts>
Creates an ErlNode. The name of the node is determined by NODE-NAME
as described below. A node-name consists of two parts: an alive-name
and a host-name, separated by an `@'. The host-name can be short
(not including the domain) or long (including the domain). Short and
long node-names must not be mixed among the nodes in a system, see
the erlang documentation for further details.
1. If the NODE-NAME contains an `@', then NODE-NAME is used
unchanged as name for the node.
2. If the NODE-NAME does not contain an `@', then the node's name
is constructed as NODE-NAME + "@" + host-name, where
host-name is either on short or long form, depending on what is
specified in the OPTS.
