Basic usage

From keplerian elements:
``
var czml = require("czml-writer");

var orbit = new czml.orbit.fromParams({
apogee: 426.9, // km
perigee: 416.2, // km
inclination: 51.65, // deg
rightAscension: 304.1, // deg
argumentOfPeriapsis: 117.8 // deg
});
var output = orbit.czml();
`

From two-line elements
`
var czml = require("czml-writer");

var tle = 'NOAA 14\n' +
'1 23455U 94089A 97320.90946019 .00000140 00000-0 10191-3 0 2621\n' +
'2 23455 99.0090 272.6745 0008546 223.1686 136.8816 14.11711747148495';
var orbit = new czml.orbit.fromTle(tle);
var output = orbit.czml();
`

To expose and use kepler.js orbit object
`
var kepler = orbit.orbit;

//angularMomentum
var angularMomentum = kepler.angularMomentum();

//radialVelocity
var radialVelocity = kepler.radialVelocity();

//eccentricity
var eccentricity = kepler.eccentricity();

//semimajorAxis
var semimajorAxis = kepler.semimajorAxis();

//semiminorAxis
var semiminorAxis = kepler.semiminorAxis();

//semilatusRectum
var semilatusRectum = kepler.semilatusRectum();

//inclination
var inclination = kepler.inclination();

//nodeLine
var nodeLine = kepler.nodeLine();

//rightAscension
var rightAscension = kepler.rightAscension();

//argumentOfPeriapsis
var argumentOfPeriapsis = kepler.argumentOfPeriapsis();

//trueAnomaly
var trueAnomaly = kepler.trueAnomaly();

//apoapsis
var apoapsis = kepler.apoapsis();

//periapsis
var periapsis = kepler.periapsis();

//period
var period = kepler.period();
