:muscle: #71 implement a method of SCObject

  - toJSON (this is used on testing)
fix tests
fix error messages
fix klass.define to allow an abbreviated constructor
fix interface to access a className property
:muscle: implement methods to pause at 'sc.lang.bytecode'

  - implement SCObject#yieldAndReset
  - implement SCObject#alwaysYield
  - fix pre-compiler to pause at these methods
  - add tests
:muscle: #71 implement methods of SCObject

  - multiChannelPerform
  - performMsg
  - tryPerform
  - dup (improve performance when looping)
  - responsTo (fix to allow argument that is an array)
  - equals
  - fin
  - streamArg
  - yield (fix to call `value` calling before 'bytecode.yield')
:muscle: implement methods to throw an error

  - sc.lang.klass.utils.notSupported
move klass definition of SCRoutine
:white_check_mark: fix tests to use SCPseq instead of SCRoutine

  before:
    Routine { [ 10, 20, 30 ].do(_.yield) }

  after:
    Pseq.new([ 10, 20, 30 ]).asStream
