`ArrayRow`	`addError(LinearSystem system, int strength)`
`ArrayRow`	`createRowDimensionRatio( SolverVariable variableA, SolverVariable variableB, SolverVariable variableC, SolverVariable variableD, float ratio )` 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( float currentWeight, float totalWeights, float nextWeight, SolverVariable variableStartA, int marginStartA, SolverVariable variableEndA, int marginEndA, SolverVariable variableStartB, int marginStartB, SolverVariable variableEndB, int marginEndB )`
`ArrayRow`	`createRowEqualMatchDimensions( float currentWeight, float totalWeights, float nextWeight, SolverVariable variableStartA, SolverVariable variableEndA, SolverVariable variableStartB, SolverVariable variableEndB )`
`ArrayRow`	`createRowEquals(SolverVariable variable, int value)`
`ArrayRow`	`createRowEquals( SolverVariable variableA, SolverVariable variableB, int margin )`
`ArrayRow`	`createRowGreaterThan(SolverVariable a, int b, SolverVariable slack)`
`ArrayRow`	`createRowGreaterThan( SolverVariable variableA, SolverVariable variableB, SolverVariable slack, int margin )`
`ArrayRow`	`createRowLowerThan( SolverVariable variableA, SolverVariable variableB, SolverVariable slack, int margin )`
`ArrayRow`	`createRowWithAngle( SolverVariable at, SolverVariable ab, SolverVariable bt, SolverVariable bb, float angleComponent )` Create a constraint to express At + (Ab-At)/2 = Bt + (Bb-Bt)/2 - angle
`SolverVariable`	`getKey()`
`void`	`initFromRow(LinearSystem.Row row)` Used to initiate a goal from a given row (to see if we can remove an extra var)
`SolverVariable`	`pickPivot(SolverVariable exclude)`
`void`	`reset()`
`void`	`updateFromFinalVariable( LinearSystem system, SolverVariable variable, boolean removeFromDefinition )`
`void`	`updateFromSynonymVariable( LinearSystem system, SolverVariable variable, boolean removeFromDefinition )`
`void`	`updateFromSystem(LinearSystem system)`
