From fa0f26c9da0dfd58238ac6c0279b54d18a505400 Mon Sep 17 00:00:00 2001
From: Michal Marcinkowski <michal.j.marcinkowski@gmail.com>
Date: Fri, 16 Jan 2015 13:06:52 -0500
Subject: [PATCH] In short, this is new: - ImageSequencer class added, requires
 planetary data service files (not added to openspace-data, too large)    :
 Given current time returns path to specific image in dataset for projection.
 - Changes to RenderablePlanetProjection class to accomodate sequencing -
 Fixed normal computation in reverse-mapping stage - Rudimental target
 recognition (will prob. become part of separate class at some point - since
 both fov & proj classes do similar things)

Next up:
- Redo pluto mockup visualization & begin spreadsheet reader for instrument-switching.
