growth-curve
============
Calculate compound growth with inflection points.
Example:
```javascript
var GrowthCurve = require('growth-curve');
var killerGrowth = new GrowthCurve({ "1": 1.02, "5": 1.10, "25": 1.20, "46": 2 });
var healthAt47 = gentleGrowth.growTo(100, 47);
var rateAt33 = gentleGrowth.getRate(33); // returns 1.2
```
###Constructor
####new GrowthCurve( *inflectionPoints* )
**inflectionPoints** is an object with rules governing the compound rates at the iterations where
they change.
###Methods
####growTo( *initial*, *target* );
Returns the value of **initial** after it has been compounded **target** number of times with
changes to the rate set according to the rules given in the constructor.
#####getPoint( *target* );
Returns the point that the growthCurve would use at the **target** iteration.
#####getRate( *target* );
Returns the rate that the growthCurve would use at the **target** iteration.
