Refactoring Project (Paul S./Marie/Jeff/Piotr/Lucas/Adam)
- Hackathon
  - Best dates: Fri Mar 13, Mon Mar 16, and Tues Mar 17
  - Planning day on Friday and two working days on Mon and Tues
  - Project status meeting (this meeting!)
- Goals:
  - Use sample meta data for something useful!
  - Parameterized data sets (plots as a function of temperature, etc)
  - Simple to represent data across parameter space
  - Abstract the data object
  - Combine plots in a meaningful way
  - Analyze groups of data as a single object
  - Create those data groups quickly
- Refactor roadmap
- Active branches:
  - SasData
    - Main refactoring branch: https://github.com/SasView/sasdata/tree/refactor_24
    - SasData refactor API: https://github.com/SasView/sasdata/tree/sasview-database
  - SasView
    - Main refactoring branch: https://github.com/SasView/sasview/tree/refactor_24
    - HDF5 file viewer: https://github.com/SasView/sasview/tree/3011-hd5-file-viewer
    - Plotting refactor (base): https://github.com/SasView/sasview/tree/plotting_refactor_tabs
    - Plotting refactor (integration): https://github.com/SasView/sasview/tree/plotting_refactor_integration
    - Plotting refactor (subplots): https://github.com/SasView/sasview/tree/plotting_refactor_integration_add_plotwidget_as_subwindow
    - Plotting refactor (perspective plots): https://github.com/SasView/sasview/tree/plotting_refactor_integration_add_fixedTabs
    - Data Explorer: https://github.com/SasView/sasview/tree/refactor24-data-explorer
    - Fixes to data explorer: https://github.com/SasView/sasview/tree/refactor24-data-explorer-fixes
- Recent work:
  - Refactor join tests: https://github.com/SasView/sasdata/pull/165
  - ND Rebinner: https://github.com/SasView/sasdata/pull/178
  - 3D data support: https://github.com/SasView/sasdata/pull/181
  - Quantity name: https://github.com/SasView/sasdata/pull/183
  - Data operations: https://github.com/SasView/sasdata/pull/184
- What's left to do:
  - Finish data loader port (red2d_reader, abs_reader, saxs_reader, sesans_reader)
  - Finish operations
  - Finish rebinning
  - Apply to slicers (might need a larger refactor here)
  - Finish trends and interpolations
  - Data explorer data representations
  - Data explorer linking gui to data
  - Data explorer trend and plot representations
  - Data explorer combining data
  - Plotting refactor integration (finalize)
  - Plotting tweaks as needed
  - Slicer GUI
  - Perspective data handling (likely last)
- Near-term projects people could tackle now:
  - Finish data loader port (red2d_reader, abs_reader, saxs_reader, sesans_reader) - Maybe already finished? - Multi-column ascii data all taken care of in base ASCII reader
  - Finish operations
  - Finish rebinning
  - Finish trends and interpolations
  - Data explorer data representations
  - Data explorer linking gui to data
  - Data explorer trend and plot representations
  - Plotting refactor integration (finalize)
