vizabi-interpolators

Interpolation algorithms shared between vizabi and waffle-server

API:

All interpolators accept the same inputs: x1, x2, y1, y2 - boundary points, x - point of interpolation
interpolator.<linear|exp|stepBefore|stepAfter|stepMiddle>(x1, x2, y1, y2, x)

and return the interpolated value y.
