much more object oriented and encapsulated. The biggest addition is
that it is now possible to support multiple DBC files being loaded at
once with each file associated to one or both buses. Note that
currently the program still does not support multiple DBC files but
the groundwork is there.
Used in signal editor to help make it easier to know what bits are
used. Added single and double precision float code where appropriate.
They weren't supported at all before. But, that code isn't really
tested yet. Added support for multiplexed signals. Most all the code
for the UI is done and some of the backend but it isn't hooked into
the actual signal processing code just yet. Updated program version
number.
