*  McStas, neutron ray-tracing package

*
* A logger of absorption as events
*
* %D
* Part of the Union components, a set of components that work together and thus
*  separates geometry and physics within McStas.
* The use of this component requires other components to be used.
*
* 1) One specifies a number of processes using process components
* 2) These are gathered into material definitions using Union_make_material
* 3) Geometries are placed using Union_box/cylinder/sphere, assigned a material
* 4) Logger and conditional components can be placed which will record what happens
* 5) A Union_master component placed after all of the above
*
* Only in step 5 will any simulation happen, and per default all geometries
*  defined before this master, but after the previous will be simulated here.
*
* There is a dedicated manual available for the Union_components
*
* This component is an absorption logger, and thus placed in point 4) above.
*
* A absorption logger will log something for each absorption event happening
*  in the geometry or geometries on which it is attached. These are specified
*  in the target_geometry string. By leaving it blank, all geometries are
*  logged, even the ones not defined at this point in the instrument file.
*  Multiple geometries are specified as a comma separated list.
*
* This absorption logger stores absorption as events, with position, velocity,
* time and weight. The Monitor_nD libraries are used to write the event files.
*
* This absorption logger needs to be placed in space, the position and velocity
*  is recorded in the coordinate system of the logger component.
*
* It is possible to attach one or more conditional components to this absorption
*  logger. Such a conditional component would impose a condition on the state of
*  the neutron after the Union_master component that executes the simulation,
*  and the absorption logger will only record the event if this condition is true.
*
* To use the logger_conditional_extend function, set it to some integer value n
*  and make and extend section to the master component that runs the geometry.
* In this extend function, logger_conditional_extend[n] is 1 if the conditional
*  stack evaluated to true, 0 if not. This way one can check what rays is logged
*  using regular McStas monitors. Only works if a conditional is applied to this
*  logger.
*
* %P
* INPUT PARAMETERS:
* target_geometry: [string] Comma separated list of geometry names that will be logged, leave empty for all volumes (even not defined yet)
* filename:        [string] Filename of produced data file
* order_total:     [1]      Only log rays that have scattered n times, -1 for all orders
* order_volume:    [1]      Only log rays that have scattered n times in the same geometry, -1 for all orders
* logger_conditional_extend_index: [1] If a conditional is used with this logger, the result of each conditional calculation can be made available in extend as a array called "logger_conditional_extend", and one would then access logger_conditional_extend[n] if logger_conditional_extend_index is set to n
* init:            [string] Name of Union_init component (typically "init", default)
