Initial design

The app should allow people to advance through the workflow only after entering some valid input;

Login Screen:

---

Enter Patient Info:

---

Select Area of Body:

---

Use Native Application to Capture Image

It would be nice here to have a view after using the native application that previews the image and allows retakes.

---

Select reference object, wound length, wound width on image.

The background here should be the image taken previously. The user will use their finger to indicate two points for each of the reference object, wound length, and wound max width. The icons indicating each of the above should begin as red indicating attention required, should become bold or pop out a little bit when selected, and once two points are selected become green. The advancement arrow should not be active unless all 3 icons are green.

---

Confirm and send.

Display the image, with all selection points superimposed on it, as well as the patient data and wound location selected. There should be a send button of course.
