removed proof of concept. Made it work for all VMMs of all hybrids.

This commit was done with an inescrupulous "git add ." after several
radical modifications.

Anyway, the API was radically modified and basically the old way the
code worked does not make any sense anymore.

The desired architecture is the following: the API is going to be used
as a class component. Each parameter will be created according to the
desired number of enabled hybrids.

Each parameter should use one simple API function. No information about
the VMM or hybrids itself is stored in the VMMTbl class unless extremely
needed.

This commit leaves a few old parameters that should be removed in the
future such as ADC_VALUE_VMM1, READ_ADC_VMMS, etc. This is only to serve
as a reminder to add those later.

In this moment we are using only hybrid 0, this must be changed in the future
