layer_orthogonal_to: Create Orthogonal Layer
In tpq/caress: Caress, a Gentler Introduction to Keras

This function makes the "target" layer orthogonal to the "reference" layer so that it cannot predict the "reference". In other words, the "target" layer will equal the "reference" layer when the "target" is orthogonal to the "reference".

1	layer_orthogonal_to(target, reference, name = NULL)

`target`	The incoming layer with predictive power.
`reference`	The incoming layer you do not want to predict.
`name`	A string. The prefix label for all layers.
