** This template allows to mix in a \c bind(...) function.

** Thereby, the correct number and types of arguments is derived

** according to the function signature given as template parameter.

** This helper template is used for the ArgumentHolder and generally
|

|
** for binding arguments for Proc-Layer commands.
