Hard-Coded and Unnecessary segments should be removed

Current Setup:
There is a lot of hard coding which brings a lot of problems when trying to generalize the framework across multiple settings.

To be introduced:
Code will be cleaned and hardcoded segments will be removed, proper parameterization in Configs will be used for all the variables and hyperparameters.

Major Changes:
The overall task of running custom settings with the default config template will be much easy after this.

Eventually, this will be progressed with #157 and will also resolve #43
