Mantaflow [Part 2]: Added fluid wrapper files
Files from /intern/mantaflow handle the communication between core Blender code and Mantaflow itself. It's the bridge to communicate with Mantas Python functions. Code from /intern/mantaflow/intern/strings/ is pure Manta code and would likely need less attention in the review.
