Remove unnecessary/redundant code

[anujsinha3]

A few functions and Python files are not being used/ duplicate in the workflow. The task is to identify these files, analyze their use-case(present and future), and if not required delete these chunks of code.

Examples:

• There are two files with the same functionality "incremental_clustering.py" and "IncrementalClustering.py".

• update_duration() in "UpdateStayDuraction.py" and "util_func.py"

• Identify redundancy / unused code chunks

• Analyze differences between redundant files/functions.

• Check if duplicate code chunk is present

• Remove the code for duplicate/ununsed code chunks.
