Caching support. Separate views.py in 2 files

This commit adds the Flask-Caching module to the software stack and
enables the caching of views in a wide variety of ways, but implemented
here to be simple to understand to someone new to the concept of caching
(aka me).

Various documentation and formatting was applied to all files. views.py
internal functions (mostly related to filesystem operations of the
server). have been moved into view_functions.py
