`ArrayRow!`	`addError(system: LinearSystem!, strength: Int)`
`Unit`	`clear()`
`ArrayRow!`	`createRowDimensionRatio( variableA: SolverVariable!, variableB: SolverVariable!, variableC: SolverVariable!, variableD: SolverVariable!, ratio: Float )` Create a constraint to express `A = B + (C - D)` * ratio We use this for ratio, where for example `Right = Left + (Bottom - Top) * percent`
`ArrayRow!`	`createRowEqualDimension( currentWeight: Float, totalWeights: Float, nextWeight: Float, variableStartA: SolverVariable!, marginStartA: Int, variableEndA: SolverVariable!, marginEndA: Int, variableStartB: SolverVariable!, marginStartB: Int, variableEndB: SolverVariable!, marginEndB: Int )`
`ArrayRow!`	`createRowEqualMatchDimensions( currentWeight: Float, totalWeights: Float, nextWeight: Float, variableStartA: SolverVariable!, variableEndA: SolverVariable!, variableStartB: SolverVariable!, variableEndB: SolverVariable! )`
`ArrayRow!`	`createRowEquals(variable: SolverVariable!, value: Int)`
`ArrayRow!`	`createRowEquals( variableA: SolverVariable!, variableB: SolverVariable!, margin: Int )`
`ArrayRow!`	`createRowGreaterThan(a: SolverVariable!, b: Int, slack: SolverVariable!)`
`ArrayRow!`	`createRowGreaterThan( variableA: SolverVariable!, variableB: SolverVariable!, slack: SolverVariable!, margin: Int )`
`ArrayRow!`	`createRowLowerThan( variableA: SolverVariable!, variableB: SolverVariable!, slack: SolverVariable!, margin: Int )`
`ArrayRow!`	`createRowWithAngle( at: SolverVariable!, ab: SolverVariable!, bt: SolverVariable!, bb: SolverVariable!, angleComponent: Float )` Create a constraint to express At + (Ab-At)/2 = Bt + (Bb-Bt)/2 - angle
`SolverVariable!`	`getKey()`
`SolverVariable!`	`getPivotCandidate(system: LinearSystem!, avoid: BooleanArray!)`
`Unit`	`initFromRow(row: LinearSystem.Row!)` Used to initiate a goal from a given row (to see if we can remove an extra var)
`Boolean`	`isEmpty()`
`SolverVariable!`	`pickPivot(exclude: SolverVariable!)`
`Unit`	`reset()`
`String!`	`toString()`
`Unit`	`updateFromFinalVariable( system: LinearSystem!, variable: SolverVariable!, removeFromDefinition: Boolean )`
`Unit`	`updateFromRow( system: LinearSystem!, definition: ArrayRow!, removeFromDefinition: Boolean )`
