Input generator

[AlexS12]

• Types for basic inputs tested and documented
• Type composition
• Code a FCS type that can be passed to propagator to provide the inputs
• Define a ControlsStream type containing Inputs with a getter to obtain controls at a certain instant
• Define a Controls type that can be used to set fcs
• Include FCS inside aircraft.
• Define a convert method to transform from Controls to ControlsStream (with ConstantInput) Is it erally necessary now? Let's wait and see what seems more natural when setting streams for integration.
• Adapt trimmer to receive Controls and return Controls
  • Adapt trimmer doc. Remove references to FCS, add Controls
• Remove *_controls_trimmer methods.
• allow_out_of_range_controls and its error as FCS configuration
  • Avoid mutable struct opened issue Use boundaries in optimization process for trimmer #66
• calculate_aircraft receiving controls argument instead of setting fcs outside
• Open an issue to think about including Control in Controls and to think about the interaction of Controls and FCS. Opened Interaction between Control, Controls and FCS #67
