find and execute trove migrations

trove_migrations.rb

# load all migrations
Dir[Rails.root.join('db/migrate/*.rb')].each { |f| require f }

#find the trove migrations classes
# and the corresponding file
# sort by file
# instantiate
# and invoke change
# rescuing from any exception.

trove_migrations = Trove::BaseMigration.subclasses.collect { |c| 
  [c] + Dir[Rails.root.join("db/migrate/*#{c.name.tableize.singularize.gsub('trofe','trove')}*.rb")]

  begin
    mig = c.new
    if mig.respond_to? :change
      mig.change
    else

# TODO dump schema to trove_schema.rb

Next step would be to dump the schema,
then at start of tests create the trove schema from trove_schema.rb
