[codingblazer]

Currently, most of files in our project are not formatted properly as per coding guidelines.
@opticod Should I send PR for this ?

Most of the files are formatted. Some recent addition of new codes from new contributors may had slightly unformatted it. Will reformat them while merging into master. Closing it now.
