Parameterization Framework for parameterized model creation and handling. This
is a lightweight framework for using parameterized models.

Features:
* Easy model creation with parameters
* Fast optimized access of parameters for optimization routines
* Memory efficient storage of parameters (only one copy in memory)
* Renaming of parameters
* Intuitive printing of models and parameters
* Gradient saving directly inside parameters
* Gradient checking of parameters
* Optimization of parameters
* Jupyter notebook integration
* Efficient storage of models, for reloading
* Efficient caching included
