This commit does not introduce any new functionality w.r.t previous commit. But it fixes few things. They are listed below: 1. Guard Bands in header files are fixed 2. Header files contains function definition comments. These are same as in source file. Maintaining same comment at two locations is unnecessary. These are removed. 3. Improved consistency and code indentation 4. Removed comments that dont align with implementation 5. Grouped headers of a workspace together
