Whitestone.execute

Executes the current test scope recursively. A SCOPE is a collection of D blocks, and the contents of each D block is a TEST, comprising a description and a block of code. Because a test block may contain D statements within it, when a test block is run @current_scope is set to Scope.new so that newly-encountered tests can be added to it. That scope is then executed recursively. The invariant is this: @current_scope is the CURRENT scope to which tests may be added. At the end of ‘execute’, The per-test guts of this method have been extracted to execute_test so that the structure of execute is easier to see. execute_test contains lots of exception handling and comments.
