Please check if the PR fulfills these requirements
Does this PR already have an issue describing the problem?
No.
What kind of change does this PR introduce?
Fix.
What is the current behavior?
The node of an isolated IIDM equipment (a connectable not linked to any other element either through switch or internal connection) isn't exported to CGMES. This leads to a cardinality issue in the CGMES EQ file where the terminal of the isolated equipment doesn't have a ConnectivityNode association.
What is the new behavior (if this is a feature change)?
The node of an isolated IIDM equipment is exported to CGMES.
Does this PR introduce a breaking change or deprecate an API?
Other information:
Nodes are now exported in order of their number. This shall ensure that nodes are exported in the same order they have been imported and thus in the case of a round-trip import/export the numbers should be the same.
