/** @brief class LocalTangentSpaceAlignment used to embed
* data using Local Tangent Space Alignment (LTSA)
* algorithm as described in:
*
* Zhang, Z., & Zha, H. (2002). Principal Manifolds
* and Nonlinear Dimension Reduction via Local Tangent Space Alignment.
* Journal of Shanghai University English Edition, 8(4), 406-424. SIAM.
* Retrieved from http://arxiv.org/abs/cs/0212008
*
* This algorithm is pretty stable for variations of k parameter value but
* be sure it is set with a consistent value (at least 3-5) for reasonable
* results.
*
* Uses implementation from the Tapkee library.
