[dlersch]

Migrate project to this repo. Start with data parser and inherit from core class

[dlersch]

• Implement data parser for the HallD punzinet project.
• The input data are pandas dataframes. Therefore, the parser is a pandas parser.
• The parser inherits from the datascience core: https://github.com/JeffersonLab/jlab_datascience_core/tree/1-implement-core-base
• Wrote unit-test that produces multiple .csv files that are read into the parser and merged into one data frame
• Shown below is a plot from the unit-test, as an additional sanity check
