Dave C-J 0b49b2cdda Add parser function nodes for XML, JSON and CSV.
Each is dual function - pass in (for example) and get out a js object, pass in a js object and get back out the xml string.
The CSV node must be configured with a column template that specifys the required property names for that column (csv->js), or the properties of the object that should be made into the csv (js->csv)

<p>A function that parses the <b>msg.payload</b> to convert csv to/from a javascript object. Places the result in the payload.</p>
<p>If the input is a string it tries to parse it as CSV and creates a javascript object.</p>
<p>If the input is a javascript object it tries to build a CSV string.</p>
<p>A columns template MUST be specified that contains the ordered list of column headers. For csv input these become the property names.
For csv output these specify the properties to extract from the object and the order for the csv.</p>
<p><b>Note:</b> the columns should always be specified comma separated - even if another separator is chosen for the data.</p>
