symmetrize a triangular mesh

retroDeformMesh(mesh, mat, pairedLM, hmult = 5, alpha = 0.01,
  rot = TRUE, lambda = 1e-08, threads = 0)

`mesh`	triangular mesh of class mesh3d
`mat`	matrix with bilateral landmarks
`pairedLM`	2-column integer matrix with the 1st columns containing row indices of left side landmarks and 2nd column the right hand landmarks
`hmult`	damping factor for calculating local weights which is calculated as `humult` times the average squared distance between a landmark and its closest neighbor (on each side).
`alpha`	factor controlling spacing along x-axis
`rot`	logical: if TRUE the deformed landmarks are rotated back onto the original ones
`lambda`	control parameter passed to `tps3d`
`threads`	integer: number of threads to use for TPS deform

this function performs retroDeform3d and deforms the mesh accordingly using the function tps3d.

`mesh`	symmetrized mesh
`landmarks`	a list containing the deformed and original landmarks
