New Module: DepositionPointCharge

From README.md:

Module which deposits a defined number of charge carriers at a specific point within the active volume the detector. The number of charge carriers to be deposited can be specified in the configuration.

This module supports three different deposition models:

• In the point model, charge carriers are always deposited at the exact same position, specified via the position parameter, in every event of the simulation. This model ist mostly interesting for development of new charge transport algorithms, where the initial position of charge carriers should be known exactly.
• In the scan model, the position where charge carriers are deposited changes with every event. The scanning positions are distributed such, that the volume of one pixel cell is homogeneously scanned. The total number of positions is taken from the total number of events configured for the simulation. If this number doesn't allow for a full illumination, a warning is printed, suggesting a different number of events. The pixel volume to be scanned is always placed at the center of the active sensor area. The scan model can be used to generate sensor response templates for fast simulations by generating a lookup table from the final simulation results.
• The mip model allows to deposit charge carriers along a straight line through the sensor, perpendicular to its surface. Charge carriers are deposited linearly along this line with 80 electron-hole pairs per micrometer. The number of steps through the sensor can be configured using the number_of_steps parameter.

Monte Carlo particles are generated at the respective positions, bearing a particle ID of -1. All charge carriers are deposited at time zero, i.e. at the beginning of the event.

Parameters

• number_of_charges: Number of charges to deposit inside the sensor. Defaults to 1. Only used for models point and scan.
• number_of_steps: Number of steps over the full sensor thickness at which charge carriers are deposited. Only used for mip model. Defaults to 100.
• model: Model according to which charge carriers are deposited. For point, charge carriers are deposited at a specific point for every event. For scan, the point where charge carriers are deposited changes for every event. For mip, charge carriers are deposited along a line through the full sensor thickness. Defaults to point.
• position: Position in local coordinates of the sensor, where charge carriers should be deposited. Expects three values for local-x, local-y and local-z position in the sensor volume and defaults to 0um 0um 0um, i.e. the center of first (lower left) pixel. Only used for the point and mip models, the latter only uses the x and y coordinates.
