Improved Keyframe Performance ( #197 )
...
* Refactor of Coorindate and Keyframe optimized for performance (much faster than previously). Also refactored FrameMapper to not use a Keyframe, and to only process frame mapping when needed... speeding up Json loading of project files.
* Fixing FrameMapper linear calculation to match existing Keyframe calculation
* Fixing Keyframe to pass original unit tests, and correctly calculate the Keyframe repeat fractions and deltas.
* Small refactor of time mapped logic in Clip.cpp

Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames)

Replaced all copyright and licensing to reflect AGPLv3 license. Also, added a bad ass version header, which is now integrated into CMake as well. A single place to indicate version and ABI/API compatibility.

Added JSON change method, which accepts a diff / sync JSON array, and applies the changes to a timeline and timeline associated properties and items. Also fixed many bugs on JSON type checking.

Removed unneeded Json from Keyframes, Points, and Coordinates... and also optimized a Keyframe with 1 point to use CONSTANT interpolation mode.

Added license and copyright to all files. Improved many examples and documentation. Refactored the Coordinate() object, to move a few properties to methods.

Added delta() to a coordinate, to track the change in unique value on the Y axis. This helps in time mapping, to track how many frames have been skipped.

Improved the Keyframe and Coordinate classes, to also track the direction and a fraction representing the number of times a frame is repeated. This will allow the time mapping to slow down audio and reverse the waveforms when necessary.
