Event Log Handler

The first feature is about handling an event log when it comes into our framework.

First, our system should accept only the following extensions:

2. CSV
3. parquet
4. xls
5. XES
6. xlsx

Second, we should convert the file to a dataframe to clean it up. (Let's discuss the clean up)

Third, we should get get a list of columns to give to the user, then let the user choose a column for case_id, activity_name, timestamp and resource.

Then we move on to the Knowledge Graph Feature, which will be discussed in another issue
