Dancer2::Core::MIME - Class to ease manipulation of MIME types
=head1 VERSION
version 1.0.0
=head1 SYNOPSIS
use Dancer2::Core::MIME;
my $mime = Dancer2::Core::MIME->new();
# get mime type for an alias
my $type = $mime->for_name('css');
# set a new mime type
my $type = $mime->add_type( foo => 'text/foo' );
# set a mime type alias
my $alias = $mime->add_alias( f => 'foo' );
# get mime type for a file (based on extension)
my $file = $mime->for_file( "foo.bar" );
# set the $thing into a content $type.
my $type = $mime->name_or_type($thing);
# get current defined default mime type
my $type = $mime->default;
# set the default mime type using config.yml
# or using the set keyword
set default_mime_type => 'text/plain';
=head1 DESCRIPTION
Dancer2::Core::MIME is a thin wrapper around L<MIME::Types> providing helpful
methods for MIME handling.
=head1 ATTRIBUTES
=head2 custom_types
Custom user-defined MIME types that are added the with C<add_type>.

=head2 add_type
This method adds the new MIME type.
=head2 add_alias
The C<add_alias> sets a MIME type alias.
=head2 for_name
The method C<for_name> gets MIME type for an alias.
=head2 for_file
This method gets MIME type for a file based on extension.
=head2 name_or_type
This method sets the customized MIME name or default MIME type into a content
