Added the point actor with required geometry, material and test cases.

Thank you

Hello,
Modified point actor and also added the maker actor. Here is the screenshot of the marker actor.

Thanks

I have left a lot of comments on this

Also @ManishReddyR why do we see the borders changing its colors while moving the scroll wheel

Its due to the over lapping of multiple actors at a time.

The PR looks good but there are some docstring changes required and some methods needs refractoring.

Thanks for review @maharshi-gor

I made the changes which you have suggested.

Just fix one small comment on the marker actor method parameters.
