Sine

Non-compatible changes:

• More PEP8 compliant:
  • func_gen() -> FuncGen()
  • func_gen_channel() -> FuncGenChannel()
  • All lines < 100 characters (mostly < 80)
• No more enable/disable_frequency_lock(), now set_frequency_lock()
• Settings dictionary now contains tuples of value and unit, e.g. settings = {"amplitude": (3, "Vpp"), ..}

New features:

• Implemented set_settings() in both FuncGen and FuncGenChannel that takes a settings dictionary as input
• get/set_output() links to get/set_output_state()

Other:

• More examples
• Expanded README
