### Description

Orthogonally projects samples onto trajectory

### Usage

    .project_ortho(cl, g, X)

`g` | Trajectory tree; igraph object
`X` | Lower dimensional ordination of trajectory samples

### Value

A `list` containing the following components:

``Y`` | Projection
``X.c`` | Mediancentres
``lambda`` | Projection lambda (position: inside/outside of edge)
