[Architecture] Updated, simplified PCP API

[Antranig Basman]

I've updated my pull request at https://github.com/GPII/universal/pull/549 to incorporate a further 
simplified version of the PCP API, which is more closely focused on the needs of the UI. This now encodes 
the model state corresponding to the settings widgets directly rather than this information being 
synthesized from excerpts of payloads taken around the system. I've updated the PCP API "work in progress" 
Google Doc to describe this API at 
https://docs.google.com/document/d/1c7QWlh-CFmkdERja7m0VRby50rySAkAP9eLGNiSlZGE/edit#
There is another example of a test payload showing an update to an application-scoped setting at 
https://github.com/amb26/universal/blob/dcdd43ff551eac2218f8a7552a0a6c3422be7d79/gpii/node_modules/flowManager/test/PCPChannelTests.js#L32
I had a chat with Georgi this morning who confirmed he thought the new API would be easy to work with. I 
will be working this afternoon for architectural support for
https://issues.gpii.net/browse/GPII-2608 - "Select preference sets" which can be done with the current 
architecture.
Support for https://issues.gpii.net/browse/GPII-2607 will continue after Kaspar returns on Monday - this 
requires some further rework of the core architecture to support the flow of updates to settings propagated 
to the running system. Work can progress on this issue in the meantime by means of mocks and tests.


There will be discussions and updates on these and other PCP related issues at the PCP status meeting which 
is upcoming shortly.


Cheers,

Antranig

Re: [Architecture] Alternatives to the "marked" markdown renderer...

[Tony Atkins]

Hi, All.

I have created pulls against gpii-handlebars
 and infusion-docs
 to migrate to
markdown-it.  Thus far my experience with markdown-it has been pretty
positive, it was basically a drop-in replacement for marked with one minor
configuration change (enabling html, which is disabled by default).

Cheers,


Tony
