Calculate geolocations by light using template matching. 
 The routine uses a calibration free optimization of a sky illuminance model to 
 determine locations robustly using a template matching approach,
 as described by Ekstrom (2004) <https://nipr.repo.nii.ac.jp/records/2496>,
 and behaviourly informed constraints (step-selection).

'Slack' <https://slack.com/> provides a service for teams to
    collaborate by sharing messages, images, links, files and more.
    Functions are provided that make it possible to interact with the
    'Slack' platform 'API'. When you need to share information or data
    from R, rather than resort to copy/ paste in e-mails or other services
    like 'Skype' <https://www.skype.com/en/>, you can use this package to
    send well-formatted output from multiple R objects and expressions to
    all teammates at the same time with little effort. You can also send
    images from the current graphics device, R objects, and upload files.

Data structures and algorithms for sparse arrays and matrices,
  based on index arrays and simple triplet representations, respectively.

Slanted matrices and ordered clustering for better visualization of similarity data.

Alternative to using withCallingHandlers() in the simple case of catch 
  and rethrow. The `%!%` operator evaluates the expression on its left hand side, 
  and if an error occurs, the right hand side is used to construct a new error
  that embeds the original error.

Allows users to list data structures using path-based navigation. 
    Provides intuitive methods for storing, accessing,
    and manipulating nested data through simple path strings.
    Key features include strict mode validation, path existence checking, recursive
    operations, and automatic parent-level creation. Designed for use cases requiring
    organized storage of complex nested data while maintaining simple access patterns.
    Particularly useful for configuration management, nested settings, and any
    application where data naturally forms a tree-like structure.
