added subtractScalar

[vrushaket]

Hello @josdejong,
I have added the implementation for subtractScalar, please have a look.
This will help solve PR #2643

Thanks a lot @vrushaket! This looks good.

As a bonus, it maybe interesting to look through the code base for places where subtract is used but only for scalars. If so, we can replace it with subtractScalar which should be good for performance.

Absolutely. I was also thinking of the same. I will make necessary changes, to make it happen.

@josdejong , all changes have been committed.
Please check.

Thanks for the updates @vrushaket , this looks good! I'm sure we gained some performance improvements with this, though I'm not sure how significant it is.
