Story 2.5

[nailahi]

As a student user, I want the code blocks available to me to reside in a clearly marked block inventory section, so that I never get confused about where I get my blocks and where I built my solutions.
Acceptance Criteria:
• The block inventory section will be labeled and clearly separated from other parts of the page.
• The block inventory section will be neatly organized to ensure code blocks can be easily seen
and selected.
• The block inventory section will indicate the remaining quantity of blocks where needed and
adjust this number as the user works.
• Blocks will be able to be dragged from this section into the workspace if they are available.
