示例1: _align
/** performs a single alignment of the measurement to the model.
* The model needs to be added using addToModel before this call.
*
* @param measurement - the mesh that needs to be matched
* @param max_iter - maximum number of iterations
* @param min_mse - minimum average square distance between points after which to stop
* @param min_mse_diff - minimum difference in average square distance between points after which to stop
* @param overlap - percentage of overlap, range between [0..1]. A value of
* 0.95 will discard 5% of the pairs with the worst matches
