module for easy database connections for Dancer2 applications

Dancer2::Plugin::Database Provides an easy way to obtain a connected DBI database handle by simply calling the database keyword within your Dancer2 application

The module returns a Dancer::Plugin::Database::Core::Handle object, which is a subclass of DBI's `DBI::db' connection handle object, so it does everything you'd expect to do with DBI, but also adds a few convenience methods.

It takes care of ensuring that the database handle is still connected and valid. If the handle was last asked for more than `connection_check_threshold' seconds ago, it will check that the connection is still alive, using either the `$dbh->ping' method if the DBD driver supports it, or performing a simple no-op query against the database if not. If the connection has gone away, a new connection will be obtained and returned. This avoids any problems for a long-running script where the connection to the database might go away.

Care is taken that handles are not shared across processes/threads, so this should be thread-safe with no issues with transactions etc.
