[code-reflection] Integrated: Converting healing brush to use HAT also offered a headless variant f…

[Gary Frost]

Offer a headless violajones example for docker testing

This push also includes intital conversion of HealingBrush to use HAT iface buffers.  Still 100% java code, but using the HAT buffers is step 1 to converting to use HAT. 

This is a good candicate, as it takes 8 seconds to locate a match in a large image. This loop is embarissingly parallel.  So hi hopes for this demo.
