Linear Programming For Minimal Cost Solution **DO NOT MERGE**

[philip-sterne]

Partial port of YALPS to dart. This allows us to suggest the minimum cost solution for feeding, which meets the necessary feeding guidelines.

• Runs the yalps algorithm to calculate the optimal feed based on the available fodder and concentrate items
• Constraints are currently hardcoded, will adapt to use the actual cow requirements constraint

Next steps:

• Prof. Sterne mentioned something about needing to change the units to have a sensible solution since CP, NDF, Ca, and P Intake requirements depend on (are percentages of) DM. So keep everything in kg/day in the solver's constraints.
        I think this affects deciding what the constraints for the solver will be: keep in kg/day and calculate the constraints for each given the DM requirements.
