Algebra-with-sympy

Versions 0.11.0. Simplified control of code and pretty-printed output that works for both `Equations` and all Sympy `Expressions`. `Equation` aware `solve()` now implemented.
Also available on pypi: `pip install Algebra-with-SymPy==0.11.0`.

- Documentation updates and fixes.
- Significantly increased test coverage (~98%).
- Support for Eqn.rewrite(Add)
- Solving (e.g. solve(Eqn,x)) now supported fully. Still experimental.
- Bug fix: latex printing now supports custom printer.
- Substitution into an Equation using Equations is now supported (e.g. eq1.subs(eq2, eq3, ...)).
- algebra_with_sympy.__version__ is now available for version checking within python.
- Bug fix: preparsing for = syntax no longer blocks obj? syntax for getting docstrings in ipython.
- More robust determination of equation names for labeling.

Release for compatibility with `sympy>=1.11`.
Can also be installed from PyPi: `pip install Algebra-with-SymPy==0.9.4`.

New shorthand syntax for defining equations in IPython and Jupyter environments: `eq_name=eq.lhs=eq.rhs`.

Also available from pypi: `pip install Algebra-with-SymPy==0.9.2`.
