Parameterization Framework for parameterized model creation and handling.

This is a lightweight framework for using parameterized models.

See examples model in paramz.examples.<tab>

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
