 * @param {String} str String to split.
 * @param {RegExp|String} separator Regex or string to use for separating the string.
 * @param {Number} [limit] Maximum number of items to include in the result array.
 * @returns {Array} Array of substrings.
 * @example
 *
 * // Basic use
 * split('a b c d', ' ');
 * // -> ['a', 'b', 'c', 'd']
 *
 * // With limit
 * split('a b c d', ' ', 2);
 * // -> ['a', 'b']

     * Observable.

     * // will log a MouseEvent object to the console. If the result is less

 * a delay-like operator since output emissions do not occur at the same time as
 * they did on the source Observable. Optionally takes a {@link IScheduler} for

/**
 * @class GeoCoords
 *
 * @classdesc Converts coordinates between the geodetic (WGS84),
 * Earth-Centered, Earth-Fixed (ECEF) and local topocentric
 * East, North, Up (ENU) reference frames.
 *
 * The WGS84 has latitude (degrees), longitude (degrees) and
 * altitude (meters) values.
 *
 * The ECEF Z-axis pierces the north pole and the
 * XY-axis defines the equatorial plane. The X-axis extends
 * from the geocenter to the intersection of the Equator and
 * the Greenwich Meridian. All values in meters.
 *
 * The WGS84 parameters are:
 *
 * a = 6378137
 * b = a * (1 - f)
 * f = 1 / 298.257223563
 * e = Math.sqrt((a^2 - b^2) / a^2)
 * e' = Math.sqrt((a^2 - b^2) / b^2)
 *
 * The WGS84 to ECEF conversion is performed using the following:
 *
 * X = (N - h) * cos(phi) * cos(lambda)
 * Y = (N + h) * cos(phi) * sin(lambda)
 * Z = (b^2 * N / a^2 + h) * sin(phi)
 *
 * where
 *
 * phi = latitude
 * lambda = longitude
 * h = height above ellipsoid (altitude)
 * N = Radius of curvature (meters)
 *   = a / Math.sqrt(1 - e^2 * sin(phi)^2)
 *
 * The ECEF to WGS84 conversion is performed using the following:
 *
 * phi = arctan((Z + e'^2 * b * sin(theta)^3) / (p - e^2 * a * cos(theta)^3))
 * lambda = arctan(Y / X)
 * h = p / cos(phi) - N
 *
 * where
 *
 * p = Math.sqrt(X^2 + Y^2)
 * theta = arctan(Z * a / p * b)
 *
 * In the ENU reference frame the x-axis points to the
 * East, the y-axis to the North and the z-axis Up. All values
 * in meters.
 *
 * The ECEF to ENU conversion is performed using the following:
 *
 * | x |   |       -sin(lambda_r)                cos(lambda_r)             0      | | X - X_r |
 * | y | = | -sin(phi_r) * cos(lambda_r)  -sin(phi_r) * sin(lambda_r)  cos(phi_r) | | Y - Y_r |
 * | z |   |  cos(phi_r) * cos(lambda_r)   cos(phi_r) * sin(lambda_r)  sin(phi_r) | | Z - Z_r |
 *
 * where
 *
 * phi_r = latitude of reference
 * lambda_r = longitude of reference
 * X_r, Y_r, Z_r = ECEF coordinates of reference
 *
 * The ENU to ECEF conversion is performed by solving the above equation for X, Y, Z.
 *
 * WGS84 to ENU and ENU to WGS84 are two step conversions with ECEF calculated in
 * the first step for both conversions.
