Anvil::Tools::Get
Provides all methods related to getting access to frequently used data.
=head1 SYNOPSIS
use Anvil::Tools;

my $anvil = Anvil::Tools->new();
# Access to methods using '$anvil->Get->X'.
#
# Example using 'date_and_time()';
my $date = $anvil->Get->date_and_time({...});

=head2 anvil_version
This reads to C<< VERSION >> file of a local or remote machine. If the version file isn't found, C<< 0 >> is returned.
Parameters;
=head3 password (optional)
This is the password to use when connecting to a remote machine. If not set, but C<< target >> is, an attempt to connect without a password will be made.
=head3 port (optional)
This is the TCP port to use when connecting to a remote machine. If not set, but C<< target >> is, C<< 22 >> will be used.
=head3 remote_user (optional, default root)
If C<< target >> is set, this will be the user we connect to the remote machine as.
=head3 target (optional)
This is the IP or host name of the machine to read the version of. If this is not set, the local system's version is checked.

=head2 date_and_time
This method returns the date and/or time using either the current time, or a specified unix time.
NOTE: This only returns times in 24-hour notation.
=head2 Parameters;
=head3 date_only (optional)
If set, only the date will be returned (in C<< yyyy/mm/dd >> format).
=head3 file_name (optional)
When set, the date and/or time returned in a string more useful in file names. Specifically, it will replace spaces with 'C<< _ >>' and 'C<< : >>' and 'C<< / >>' for 'C<< - >>'. This will result in a string in the format like 'C<< yyyy-mm-dd_hh-mm-ss >>'.
=head3 offset (optional)
If set to a signed number, it will add or subtract the number of seconds from the 'C<< use_time >>' before processing.
=head3 use_time (optional)
This can be set to a unix timestamp. If it is not set, the current time is used.
=head3 time_only (optional)
If set, only the time will be returned (in C<< hh:mm:ss >> format).
=head3 use_utc (optional)
If set, C<< gmtime >> is used instead of C<< localtime >>. The effect of this is that GMTime (greenwhich mean time, UTC-0) is used instead of the local system's time zone.

=head2 switches
This reads in the command line switches used to invoke the parent program.
It takes no arguments, and data is stored in 'C<< $anvil->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<< $anvil->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<< $anvil->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.

This method returns a new v4 UUID (using 'UUID::Tiny').
Parameters;
=head3 short (optional, default '0')
This returns just the first 8 bytes of the uuid. For example, if the generated UUID is C<< 9e4b3f7c-5a98-40b6-9c34-84fdb24ddd30 >>, only C<< 9e4b3f7c >> is returned.
