Layouts Types

There are two type of layouts in PTC.

1. The usual LAYOUT made of FIBREs.
2. The NODE_LAYOUT which depends on the LAYOUT

A LAYOUT ``R'' contains a NODE_LAYOUT R%T if once elects to create this layout. Neither radiation nor spin nor beam-beam lens can be used with L. One must create the NODE_LAYOUT R%T.

N.B. Spin, Classical Radiation, Stochastic Radiation, distributed apertures, Beam-Beam kicks and magnet modulation all require the NODE_LAYOUT.
