Pyphs

-
- Change Core.build_R to Core.reduce_z.
- Initialization of PHSSimulation is made at object instanciation by passing a dictionnary of list of sympy expressions.
- Rename PHSCoreMethod in PHSMethod.
- Rename PHSNumericalEval in Eval.
- Rename PHSCoreMethod in Method.
- Rename PHSNumericalCore in Numeric.
- Remove 'PHS' prefix in classes names.

- changes in PHSCore:
* core.apply_connectors => core.connect
- Improve code quality

- Improve coverage
- Implement the Thermics dictionary
- Implement CMake build system
- changes in PHSCore:
* core.apply_sub => core.substitute
* core.split_linear => core.linear_nonlinear
- changes in PHSSimulation:
* simu.fs => simu.config['fs']
* simu.init(sequ=u, seqp=p, nt=nt) => simu.init(u=u, p=p, nt=nt)
* config is no more an option to simu.init. This means the numerical object is fixed once and for all at PHSSimulation instanciation.
- PHSNumericalMethod => PHSCoreMethod
- latex/ => misc/latex/
- plots/ => misc/plots/
- simulations/ => numerics/simulations/
- cpp/ => numerics/cpp/

- Include MANIFEST.in, AUTHORS, CHANCELOG.
- Correct connectors ordering in graph analysis
- Correct state initialization in generated c++ code
- Add Beam/cantilever component
- Add Mechanics/felt component

- Add continuous integration tools (Travis CI, Codecov, Coveral, Landscape).
- Add tests.
- Use of Theano for lambdifications.
