Neural Network Symbol Recognizer 4.27

Neural Network symbol recognition system
Plugin enables you to draw collections of Symbols/Patterns which can be recognized during gameplay by a Neural Network system.
It can be used in different gameplay scenarios:
Cast a spell according to a mouse gesture
Paint a symbol on doors and unlock them if correct
Make a minigame that requires speed and precise drawing to pass
Basic functionality:
Draw different patterns (Symbols) in a plugin's window. It can be letters, digits or any abstract shape. Launch machine learning and save the result. Test drawing accuracy inside the plugin window. Then do a simple setup in Blueprints or code to be able to draw and test the drawing accuracy in a game.
Workflow for in game drawing and testing symbols accuracy:
Initialize drawing by calling a method BeginDrawing() on input PRESSED
Pass brush (cursor) location into Draw() method when moving your brush or in Tick
Call EndDrawing() to break current drawing line on input RELEASED
When a drawing is finished Test its accuracy by calling TestDrawing or GetMostAccurateSymbol
React somehow to the test result (either kill a player if failed of throw a blizzard of fireballs when succeeded)
Call ClearCanvas when current drawing is not needed and want to start new drawing.
