title: Symfony Doctrine entity overview
body: <p>Is it possible to get a report of all the mapped entities in a project?</p>
  <p>I would like a console command or an external bundle which could show me the detailed list of all the mapped entities, along with every detail about fields, types, constraints and so on.</p>
  <p>Something like this:</p>
  <h2>Product</h2>
  <pre><code>|-------|-------------|--------|----------|-------------|
  | Field | Type        | Column | Nullable | Constraints |
  |-------|-------------|--------|----------|-------------|
  | name  | string(255) | name   | no       | NotBlank    |
  |-------|-------------|--------|----------|-------------|
  | price | float       | price  | yes      | GreaterThan |
  |-------|-------------|--------|----------|-------------|
  </code></pre>
  <p>It could be very useful to get a rapid overview of a project with many entities.</p>
