Requirements for Milestone "Read and execute blocks"

Functional Requirements:

• The blocks must be read and executed in the order they are placed in the canvas. (Issue 26)
• The user should be able to start the execution of the blocks. (Issue 26)
• When the start button is clicked an array of code blocks should be created that includes the type of movement and the input value as attributes for each code block. (Issue 26)
• The blocks placed inside the "repeat x times block" should be added to that array in sequence x times, where x is the value the user specifies. (Issue 26)
