OpusVL::SysParams - Module to handle system wide parameters

The idea is to allow the storage and retrieval of system wide parameters.  The OpusVL::SysParams is the 
main interface onto this storage and provides simple get/set methods.  This uses a DBIx::Class::Schema
to store the data.  

If you want to integrate this into an existing DBIx::Class Schema you can use a Role to apply to your
schema to inject the necessary tables and a schema level sys_params object.

    # in your schema class.
    with 'OpusVL::SysParams::RolesFor::Schema';
    OpusVL::SysParams::RolesFor::Schema->setup_sysparams(__PACKAGE__);

    # now anywhere that has access to the schema can access the 
    # sys_params object.
    $schema->sys_params->get('param.name'); 

To use it stand alone you can use a regular Catalyst style config file to initialise the schema. 
If the constructor is called without a schema specified it will attempt to load up a schema based
on a config file in the catalyst style for the name 'OpusVL::SysParams'.  This config file should
have a Model::SysParams section containing the config.

    <Model::SysParams>
        connect_info dbi:Pg:dbname=test1
        connect_info user
        connect_info password
    </Model::SysParams>

Note that you must specify at least 2 connect_info parameters even if you are using SQLite otherwise
the code will crash.

Set the environment variable OPUSVL_SYSPARAMS_CONFIG if you want to make sure you know where it will 
pull it's config from.

    $ENV{OPUSVL_SYSPARAMS_CONFIG} = $filename;
