jet_cad_2d_kit_restaurant 0.1.3

The restaurant kit for jet_cad_2d plans: 69 restaurant symbols (tables, booths, bar, service, commercial kitchen, outdoor and decor), the servable ones as service units.

example/main.dart

// The restaurant kit as a host sees it. A host passes `restaurantKit` to the
// plan library -- `PlanController(kits: [restaurantKit])`, and a `PlanEditor`
// over it (the plan library's package) -- which this package does not depend
// on, nor does its example. What the example shows is the descriptor itself,
// and the library a `PlanBuild` places from: its categories, and the seated
// symbols, the numbered table units.
//
// The kit is a Flutter library (its source reads a bundled asset): the
// example is analysed with the package, and test/example_test.dart runs it.
