cosines: Direction cosines
In lorentz: The Lorentz Transform in Relativistic Physics

Given a vector of three-velocities, returns their direction cosines

1	cosines(u, drop = TRUE)

`u`	A vector of three-velocities
`drop`	Boolean, with default `TRUE` meaning to coerce return value from a one-row matrix to a vector, and `FALSE` meaning to consistently return a matrix
