Flexirest: Automatic conversion of fields to Date/DateTime

By default Flexirest will attempt to convert all fields to a Date or DateTime object if it's a string and the value matches certain regular expressions. However, on large responses this can be computationally expensive. You can disable this automatic conversion completely with:

Flexirest::Base.disable_automatic_date_parsing = true

Additionally, you can specify when mapping the methods which fields should be parsed (so you can disable it in general, then apply it to particular known fields):

class Person < Flexirest::Base
  get :all, '/people', parse_fields: [:created_at, :updated_at]
end

It is also possible to whitelist fields that should be parsed in your models, which is useful if you are instantiating these objects directly. The specified fields also apply automatically to request mapping.

class Person < Flexirest::Base
  parse_date :updated_at, :created_at
end

# to disable all mapping
class Disabled < Flexirest::Base
  parse_date :none
end

This system respects disable_automatic_date_parsing, and will default to mapping everything - unless a parse_date whitelist is specified, or automatic parsing is globally disabled.
