v0.2.1 Minor fixes

• Aligned memory for structs (according to gofmt)
• Fixed standard deviation of measurement for X and Y for Kalman2D

v0.2.0 Re-implementation **BREAKING CHANGES**

Now this package is now similar to other implementation: https://github.com/LdDl/kalman-rs
I think it is better to have same logic in both implementation (easier to find bugs and manage math)

v0.1.1 Export X-state setter

Since Kalman filter has not been exported in PointTracker, we were used to write code like this:

tracker.kf.X.Set(0, 0, pointTrackerTestData[0][0]) // x
tracker.kf.X.Set(1, 0, pointTrackerTestData[0][1]) // y
tracker.kf.X.Set(2, 0, 0)                          // vx
tracker.kf.X.Set(3, 0, 0)                          // vy

But this is bad for external libraries.
So we come up with simple setter. For mor information see: https://github.com/LdDl/kalman-filter/blob/master/point_tracker.go#L69

v0.1.0 - Initial implementation

First release:

• Initial implementation of linear Kalman filter
• Implementation (wrappings actually) of 2-D based points tracker
