Multi Feature Inserter

Inserts features from a data table into the network. The object to attach the feature to is detected by the available ids per feature.

1. No ids -> feature is attached to the graph
2. Node id -> feature is attached to node
3. Edge id -> feature is attached to edge
4. Edge and node id -> feature is attached to the end specified by the node and edge id

The name of the column is used as feature name and the feature type is determined from the column type.

The column names should not start with the prefix "knime_" since this is reserved and used for KNIME internal features such as the unique network id.
