Research direction

Start by reading the existing Get and GetAll implementations and how TableAttribute is handled. Add a Count() extension on IDbConnection that uses the mapped table name and returns the row count; done means the method is exposed consistently with the other extensions.

Written by the indexing model from the issue text.

Description

The implementation should be quite simple I believe, similar to how Get or GetAll are implemented. Here's the extension method I've been using:

public static int Count<T>(this IDbConnection connection)
{
    return connection.QuerySingle<int>($"SELECT COUNT(1) FROM {typeof(T).Name}");
}

Obviously the real implementation would need to incorporate the TableAttribute
