Linear interpolation between two angles along the shorter arc
#### interpolateAngle(from, to, t)
Parameters: from - angle in radians 0..2PI to - angle in radians 0..2PI t - interpolation ratio 0..1
``javascript
var interpolateAngle = require('interpolate-angle');
interpolateAngle(0, 2 * Math.PI, 0.5) //-> PI
interpolateAngle(-Math.PI/6, Math.PI/6, 0.5) //-> 0
interpolateAngle(Math.PI*5/3, Math.PI/3, 0.25) //-> -1/6 PI
