### Description
This module measures the efficiency of the device under test by comparing its cluster positions with the interpolated track position at the DUT.
It also comprises a range of histograms to investigate where inefficiencies might come from.
### Parameters
*`pixel_tolerance`: Parameter to discard tracks, which are extrapolated to

*`inpixel_bin_size`: Parameter to set the bin size of the in-pixel 2D efficiency histogram. This should be given in units of distance and the same value is used in both axes. Defaults to `1.0um`.

* Other:
* Value of total efficiency as `TEfficiency` including (asymmetric) error bars
* Value of total efficency as `TName` so it can be read off easily by eye from the root file
