This patch completes the implementation of the API, making the entire MMGen
code base usable as a library for external projects. A usage example can be
found in the script `examples/coin-daemon-info.py`.
Testing:
$ test/test.py -e coin_daemon_info
This patch eliminates the global configuration variables `opt` and `g`, making
all functions and class instances locally configurable. Configuration data is
passed to functions and constructors via the `cfg` parameter and made available
to methods in `self.cfg`.
Local configuration free from dependence on the command line will enable the
creation of multiple, independently configured instances of MMGen’s data
objects within a single process.
Potential applications include testing (tracking wallets configured to interact
with spawned processes, for example) and the use of MMGen as a library for
other projects.
This patch completes most of the work required to enable the API. The full
implementation will appear in a forthcoming commit.
