/**
 * @whatItDoes
 *
 * This component is the base component with the required features to be used for the nodes in a `NodeEditor`
 *
 * @howToUse
 *
 * This interface must be implemented by all the components that represent a node editor graph node,
 * to implement base internal node editor features
 *
 * Also, the ports must be explicit identified in the HTML of every GraphNode component ([attr.port-id]="port_X_id")
 *
 * ### Inputs
 * * `string` : **id** - The id of the node
 * * `PortHighlightedArgs` : **portHighlighted** - Port highlighted
 * * `PortLinkedArgs` : **internalPortLinked** - When a link is magnetized to a port during link creation drag (port id)
 * * `LinkCreatedArgs` : **linkCreated** - When a link is connected (created)
 * * `LinkRemovedArgs` : **linkRemoved** - When a link is removed
 * * `LinksChangedArgs` : **linksChanged** - When links change, used to update ports
 * * `string` : **headerIcon** - The header icon class
 * * `string` : **headerTitle** - The header title
 * * `boolean` : **isGhost** - If the aspect of the component is in "ghost" mode witch consists in a shape more rounded and more transparent
 * * `GraphNodeIOPort[]` : **inputPorts** - The input ports
 * * `GraphNodeIOPort[]` : **outputPorts** - The output ports
 * * `boolean` : **collapsed** - If the node is collapsed
 * * `boolean` : **selected** - If the node is selected
 * * `string` : **invalidLinkMessage** - The message to show when a link is invalid
 * * `function` : **internalPortMagnetizedCallback** - The callback to be executed when a port of
 * this node is magnetized with a link when user is dragging a new link
 * * `function` : **outputPortHighlightedCallback** - The callback to be executed when an output port
 * from any node in the NodeEditor is highlighted
 *
 * ### Outputs
 * * `NodeCollapsedOrExpandedArgs` : **collapseClicked** - When an option to collapse or expand this node is clicked
 * * `string` : **removeClicked** - When an option to removed this node is clicked (sends the id of the node)
 * * `PortHighlightedArgs` : **internalPortHighlighted** - When an internal port of this node is highlighted
 * * `string` : **settingsClicked** - When an option to open the settings of this node is clicked (sends the id of the node)
 * * `void` : **nodeEditorComponentResized** - When the component size (view) changes and needs to be updated
