* Added Get->switches to read in command line switches.

* Added Get->host_uuid that reads the host's UUID from dmidecode.
* Added Log->_adjust_log_level to automatically change the active log level when -V (0), -v (1), -vv (2), -vvv (3) or -vvvv (4) are passed.

+This reads in the command line switches used to invoke the parent program. 
+
+It takes no arguments, and data is stored in 'C<< $an->data->{switches}{x} >>', where 'x' is the switch used.
+
+Switches in the form 'C<< -x >>' and 'C<< --x >>' are treated the same and the corresponding 'C<< $an->data->{switches}{x} >>' will contain '#!set!#'. 
+
+Switches in the form 'C<< -x foo >>', 'C<< --x foo >>', 'C<< -x=foo >>' and 'C<< --x=foo >>' are treated the same and the corresponding 'C<< $an->data->{switches}{x} >>' will contain 'foo'. 
+
+The switches 'C<< -v >>', 'C<< -vv >>', 'C<< -vvv >>' and 'C<< -vvvv >>' will cause the active log level to automatically change to 1, 2, 3 or 4 respectively. Passing 'C<< -V >>' will set the log level to '0'.
+
+Anything after 'C<< -- >>' is treated as a raw string and is not processed.
