v0.11.0

ModiaBase v0.11.0

Diff since v0.10.0

• Moved ModiaBase.Symbolic.makeDerVar to Modia (because makeDerVar needs FloatType for
  generating type-stable code and FloatType is available in Modia but not in ModiaBase).

Non-backwards compatible changes

• EquationAndStateInfo.jl and StateSelection.jl moved to Modia (ModiaLang is merged into Modia), because
  the AST generation in these files depends on details of CodeGeneration.jl of Modia/ModiaLang.

• TestLinearEquations.jl also moved to Modia/ModiaLang.

Non-backwards compatible improvements

• Parameter values in the code are now type cast to the type of the parameter value from the
  @instantiatedModel(..) call. The benefit is that access of parameter values in the code is type stable
  and operations with the parameter value are more efficient and at run-time no memory is allocated.
  Existing models can no longer be simulated, if parameter values provided via simulate!(.., merge=xx) are not
  type compatible to their definition. For example, an error is thrown if the @instantedModel(..) uses a Float64 value and the
  simulate!(.., merge=xx) uses a Measurement{Float64} value for the same parameter.

Other improvements

• Hierarchical names in function calls supported (e.g. a.b.c.fc(..)).

• Functions can return multiple values, e.g. (tau1,tau2) = generalizedForces(derw1, derw2).

• Large speedup of symbolic transformation, if function depends on many input (and output) arguments
  (includes new operator implicitDependency(..)).

• Support for StaticArrays variables (the StaticArrays feature is kept in the generated AST).

• Support for Array variables (especially of state and tearing variables)
  where the dimension can change after @instantiateModel(..)

• Included DAE-Mode in solution of linear equation system (if DAE integrator is used and all unknowns of a linear
  equation system are part of the DAE states, solve the linear equation system during continuous integration
  via DAE solver (= usually large simulation speed-up, for larger linear equation systems)

• Improved code generation of linear equation systems lead to more efficient solution of linear equation systems.

Bug fixes

• Do no longer expand the unit macro in the AST, such as u"N", because otherwise logCode=true results in wrong code
  (previously, a u"N" definition in the model was displayed in the code as N which is not correct Julia code).
