Add Steady State (COPASI-style) to VCell through CVODE (VCellODE)

[CodeByDrescher]

Adding Steady State to VCell Release in a profound way means clearing a number of large hurdles:

• [ ] Adding Steady State capability to the VCell-ODE project .
• [ ] Adding relevant GUI windows, components, widgets, etc. for users to seamlessly run steady state. (see #1553)
• [ ] Adding results window specifically for steady state results.
• [ ] Expanding solver input files to request steady state.
• [ ] Extending / adding new output file parsing for steady state results.
• [ ] Integrating new Steady State capabilities into VCell SedML import Export.
• [ ] Expanding VCML and BioModel to accept the new Steady State simulation settings.
