Grammalecte  Check-in [ce33035715]

If you don’t want Grammalecte to modify directly the node content, add the property: `data-grammalecte_result_via_event="true"`.

With this property, Grammalecte will send an event to the node each times the text is modified within the panel.
The text can be retrieved with:

    node.addEventListener("GrammalecteResult", function (event) {
        const detail = (typeof(event.detail) === 'string') && JSON.parse(event.detail);
        if (event.detail.sType  &&  event.detail.sType == "text") {
            let sText = event.detail.sText;
        if (detail.sType  &&  detail.sType == "text") {
            let sText = detail.sText;
            ...
        }
    }


### Parse a node and get errors

    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 (for each paragraph) will be sent in a succession of events at the node.

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

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

- destination: node_id (string)

- request_identifier: a custom identifier (string) [default = ""]

Suggestions will be sent within an event at the node identified by `destination`.

    node.addEventListener("GrammalecteResult", function (event) {
        const detail = (typeof(event.detail) === 'string') && JSON.parse(event.detail);
        if (event.detail.sType  &&  event.detail.sType == "spellsugg") {
            let oResult = event.detail.oResult;
            let oInfo = event.detail.oInfo; // object containing the destination and the request_identifier
        if (detail.sType  &&  detail.sType == "spellsugg") {
            let oResult = detail.oResult;
            let oInfo = detail.oInfo; // object containing the destination and the request_identifier
            ...
        }
    }
