[Rails] [ANN] Validation Reflection plugin

[Michael Schuerig]

The validation reflection plugin adds three things

(1) Reflective access to validations
    - ModelClass.reflect_on_all_validations
    - ModelClass.reflect_on_validations_for(:property)

(2) It provides "declarative" methods for defining 
    validations based on database metadata
    - validates_presence_of_mandatory_content_columns
    - validates_lengths_of_string_attributes
    - validates_all_associated

(3) It reflects validation information into the class attributes of 
    of HTML elements generated from rhtml templates.
    See test/instance_tag_validations_test.rb for what this looks like.
    Yes, for validates_format_of it gets nasty.
