Use the Coin methods to store the initial values based on the spreadsheet. These can be a useful optimization for Calc, especially for repeated Solver runs where the user changes one input and runs Solver again. Developed with help from AI (ChatGPT and Code Copilot)
CoinMP supports the MPS-style range constraints: L row: lower <= expression <= upper G row: lower <= expression <= upper R row: lower <= expression <= upper This makes possible through some trickery to reduce the number of equations, which is useful for very big systems with many constraints. The feature was assisted with AI (Code Copilot and ChatGPT).

Unfortunately CoinMP currently doesn't use them, but in the future it may.
