org.gephi.data.attributes.api.AttributeColumn
Column is the header of a data column. It belongs to an AttributeTable and is the key to access data within AttributeRow.
It contains its index that may be used to get the appropriate value in the AttributeRow values array.
For Gephi internal implementation purposes, names of columns are restricted. They can have any name except these defined in {@link org.gephi.data.properties.PropertiesColumn PropertiesColumn} enum.
