/**
* A data representation of a Hermite Curve (see http://en.wikipedia.org/wiki/Cubic_Hermite_spline)
*
* A Hermite curve has a start and end point and tangent vectors for both of them.
* The curve will always pass through the two control points and the shape of it is controlled
* by the length and direction of the tangent vectors.  At the control points the curve will
* be facing exactly in the vector direction.
*
* As these curves change speed (speed = distance between points separated by an equal change in
* 't' value - see Hermite.getPoint) this class attempts to reduce the variation by pre-calculating
* the `accuracy` number of points on the curve. The straight-line distances to these points are stored
* in the private 'points' array, and this information is used by Hermite.findT() to convert a pixel
* distance along the curve into a 'time' value.
*
* Higher `accuracy` values will result in more even movement, but require more memory for the points
* list. 5 works, but 10 seems to be an ideal value for the length of curves found in most games on
* a desktop screen. If you use very long curves (more than 400 pixels) you may need to increase
* this value further.
*
* @class Phaser.Hermite
* @constructor
* @param {number} p1x - The x coordinate of the start of the curve.
* @param {number} p1y - The y coordinate of the start of the curve.
* @param {number} p2x - The x coordinate of the end of the curve.
* @param {number} p2y - The y coordinate of the end of the curve.
* @param {number} v1x - The x component of the tangent vector for the start of the curve.
* @param {number} v1y - The y component of the tangent vector for the start of the curve.
* @param {number} v2x - The x component of the tangent vector for the end of the curve.
* @param {number} v2y - The y component of the tangent vector for the end of the curve.
* @param {number} [accuracy=10] The amount of points to pre-calculate on the curve.
