NOTE

The files of this directory are .chf (Chrono Functions) files,
and can be loaded only from/to Chrono "Ch-function editors".

Some examples of "ch-function" editors can be seen in the 
property tab of markers (for example, the 'motion on body X 
axis' function in the 'motion' tab).

Ch-functions can be used to define motion laws for mechanical
parts, and for many other purposes.
