Add an option for saving all the input (and output) of the browser web page in localhost

[TiagoCavalcante]

Is your feature request related to a problem? Please describe.

In most cases it is desired to save the "queries", and I believe that for most use cases localhost is enough.

This would avoid losing work when reloading, or needing to copy the "queries" elsewhere so they can be reused later.

@TiagoCavalcante Is the "proof of concept" acceptable for you?
Save stores the (recursive) definition of f and Get reads it in again.

public void testSave() {

TODO the Save function must implement some regex to save all "Global*"` context names.
