IHE TF Introduction Section for Devices & Use Contexts (Home & Mobile, Hospital Enterprise, acute Point-of-Care)

With the 2019 extension of the IHE PCD scope to include both Personal Connected Health (PCH) and Device Point-of-care Interoperability (DPI) as additional to the Patient Care Devices (PCD) scope, and with the rebranding of the domain as simply "Devices", the IHE Devices TF should have an introductory section explaining these use context distinctions, a brief history of the domain - namely from PCD to DEV - and generally "What is a device?" since there are explicit exclusions (like radiological devices) and new inclusions like Software as a Medical Device.

Proposal
Add a section to the technical framework with the above mentioned content. This could be an initial article in DEV TF-1:2.
