Story 2.6

[nailahi]

As a student user, I want to be able to fill in certain portions of code blocks with my own input, so that I can alter their behavior as needed to solve a problem.
Acceptance Criteria:
• Spaces within the code in the blocks will clearly show what the user will be supplying.
• These spaces will be editable by the user after the code block is placed into the workspace
section.
• The spaces will be edited via textbox or dropdown menu, whichever is deemed more
appropriate for the block in question.
