Transform unit vectors to angular data

Transform unit vectors to angular data.

etoa(x)

`x`	A numerical matrix with directional data, i.e. unit verctors.

from the Euclidean coordinates the data are mapped to angles, expressed in rads.

A list including:

`mu`	A matrix with angles. The number of columns is one less than that of the original matrix.
