Add functioning exercise components for support. Includes test exercises to make sure they work.
ComposeDecompose: Takes a value and shows exercise with 2 inputs and hints automaticly. Can change the ammount of options it has.
Connectlines: Exercise to connect between eachother. Has two modes, sum and picture, sum uses a 1+1 style of options, and picture uses the grid layout for more complexity. Picture in the middle is currently default blocks, this has to be conversed of how it should be displayed.
PictureChoose.vue: This one shows grid with the first and second value, the correct answer must have a boolean value stating this is the correct one.
Substractvisual.vue: This one is the most loose, as it only uses the grids as visuals and answer purposes. Not more than that.
Wheremore.vue: Has two modes, less or more (if non it defaults to more), Takes a left value and a right value to create the execise.
Examples of the structure are detailed in each component. And app.vue has demo exercises for testing and visual purposes.
