    oGrammalecteAPI.parseNode("node_id")
    oGrammalecteAPI.parseNode(node)

The node can be a textarea, an editable node or an iframe. The node must have an identifier.
Results will be sent with a succession of events at the node.

    node.addEventListener("GrammalecteResult", function (event) {
        if (event.detail.sType  &&  event.detail.sType == "errors") {
        if (event.detail.sType  &&  event.detail.sType == "proofreading") {
            let oResult = event.detail.oResult; // null when the text parsing is finished
            ...
        }
    }

For the last event, `oResult` will be `null`.

                            oGrammalecte.oGCPanel.addParagraphResult(result);
                        } else {
                            oGrammalecte.oGCPanel.stopWaitIcon();
                            oGrammalecte.oGCPanel.endTimer();
                        }
                    }
                    else if (oInfo.sDestination  &&  document.getElementById(oInfo.sDestination)) {
                        const xEvent = new CustomEvent("GrammalecteResult", { detail: JSON.stringify({ sType: "errors", oResult: result, oInfo: oInfo }) });
                        const xEvent = new CustomEvent("GrammalecteResult", { detail: JSON.stringify({ sType: "proofreading", oResult: result, oInfo: oInfo }) });
                        document.getElementById(oInfo.sDestination).dispatchEvent(xEvent);
                    }
                    break;
                case "parseAndSpellcheck1":
                    if (oInfo.sDestination == "__GrammalectePanel__") {
                        oGrammalecte.oGCPanel.refreshParagraph(oInfo.sParagraphId, result);
