[code-reflection] Integrated: Added @hat/help and @hat/test-suite

[Gary Frost]

Added @hat/help (display help) 

Also @hat/test-suite to access recent test updates. 

So 

  @hat/help 
  
  @hat/test-suite:  [ffi|my|seq]-[opencl|java|cuda|mock|hip]
             @hat/test-suite ffi-opencl

   @hat/test:  [ffi|my|seq]-[opencl|java|cuda|mock|hip] classToTest (also classToTest#method)
              @hat/test ffi-opencl  hat.test.TestMatMul
               @hat/test ffi-opencl  hat.test.TestMatMul#method (note at shell we need to escape #!! )
