Find better name for the package and DataFrameWithInfo object

[lorenz-gorini]

Random ideas to break the ice:

• PreFlow (preprocessing flow),
• FrAnX (Frame Analysis Extended),
• PreLib (Preprocessing Library),
• MuFAnLib (Multiple Feature Analysis Library -> perché l'idea è di analizzare in modo automatico dataframe con molte features),
• DATIn (Data Analysis Torch Interface)

From an offline conversation, these are the proposed package names:

• CaFePro (Cached Feature Preprocessing)
• CaLMu (Cached anaLytics for Multiple feature preprocessing)
• FrAnX (Frame Analysis eXtended)
• FrAX (dataFrame Analysis eXtended)
