CSV Load example

[gopi-suvanam]

Feature Reuest There is no example to work with CSV files for data analysis. There are several examples in this repo for using the Scribbler tool including examples on charting, ML, simulation, financial calculations etc.

Solution Make an example notebook for loading CSV files and doing analysis. For details on examples look at the examples folder in the repository. An example notebook can be easily created in Scribbler using the hosted version: https://app.scribbler.live . Once the example is created put it in the examples/ folder of this repo, push and send a pull request. The example should contain:

1. loading a CSV file either using file input element or load_file function.
2. visualization including charting, showing head, group by etc.
