Add trademark for product name

[marissaAnn]

Proposed changes

Adding product name trademark to prominent locations in the documentation, see legal guidelines:

"In written documents – it is only necessary to use a symbol with the first instance of the mark, or with the most prominent placement of the mark. It is a common misconception that each and every instance of the mark should bear a trademark symbol. Overuse creates visual clutter and may detract from the aesthetic appeal of the piece. Provided there is at least one conspicuous use of the TM, SM, or ® on the face of the writing, do not be afraid to eliminate superfluous markings."

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Refactor (changes to code, which do not change application behavior)
