Generate PDF from JSON data

[harmeet-status]

We need JSON to PDF generation capability built within Spiff. We cannot reply on an external service since we will have private data.

We should construct a HTML CSS page and then convert that to PDF.

Create a connector that accepts a template name (will start with one template, for invoices) and a set of json data (that can be used to fill out the template). This means a BPMN Author can't create new templates (unless we create a separate system for them to do that). The complete PDF is returned.

We would want to create a generic invoice template that suits a range of scenarios. It would be great to build the template in a way that we can call it using 2 different methods:

Method 1 (Vendor invoicing) : Used for vendors, including bounties

• Vendor details
• Invoice addressed to
• Invoice summary
• Invoice details
• Payment total data
• Notes

Method 2 (CC invoicing) : Used for staff

• Vendor details (also includes contributor #)
• Invoice addressed to
• Invoice summary (includes invoice period)
• Invoice details (includes category field)
• Payment total data
• Notes

Method 2 can be thought of as a superset and contains all the fields where as method one had some less fields.
