Task Options

OptionParser

//on tail

properties = {
  :arg =>   # [:mandatory, :optional, :switch, list, [] indicating selection]
  :cast =>  # Class
  :block => # perform something novel... by default the block simply sets config with result. } 

Converting to properties

  no cast:
  default indicated by &type.

  then no arg, for cast:
    Bloolean => switch
    Array => list

Error if list and cast to something other than Array?

type: string, boolean, float, integer, array, selection (in?), yaml

Usage

Pickup documentation from RDoc... no help messages specified ( add later ? )

Evaluate options in context with: config, argv, option class

API

opt defines option properties, no actual config. Block, same as above. Non-configs are simply passed into task.config and stored.

Need an class_options class to hold this information. Should be separate from ClassConfiguration as they apply in different contexts.
