Tidied up the displays so they look good on iPhone 11 and iPad (and prepared for macOS... yes, there is now a Mac version).

Fixed the GAMS export, which was working when reserves and losses were included (the sample that was used for testing), but failing for the simpler models when reserves and/or losses were disabled. Also some minor refactoring of the code, all appears to be well, but please report any issues.

Fixes a bug that caused data entry corruption when using a non-English language setting.

2.01 is a minor change to fix blurry screenshots on the load/save displays. It is built on top of version 2.0, which added the following: • Multiple electrical islands, with island based risk and reserve. • HVDC branch component to connect islands. • HVDC branch can set risk in receiving island. HVDC risk is modelled separately from AC risk to allow for reserve sharing. • HVDC risk can be mitigated by adding parallel HVDC branch. The spare capacity on the parallel branch provides a risk subtractor. • HVDC can share reserve between islands to cover AC risk. This reserve sharing is subject to a capacity constraint, which directionally limits the sum of energy and reserve to the capacity of the HVDC branch. Also: • Island colour is selectable. • Dead component identification. Dead components are excluded from the solve. • Risk unit and risk setter indication on main display. • When a bus component is moved, attached branch components are moved or re-sized. • Option to hide branch names and bus angles.

Added warning that saving tableaux can slow the solve and therefore to only apply this setting if detailed simplex operations need to be saved for export and analysis. Also, if the save tableaux option is not set to None then it will be highlighted red. Removed the delete confirmation alert because delete is already a two step process, i.e., long press -> wobble -> tap; including the alert adds an unnecessary third step
