Added a conditional_field to all the commands that work on a selection of nodes or elements. Changed gfx_select to use this function for nodes/data/elements/faces/lines. Added a definition of "true" to Computed_fields.  A field is true if it is able to be evaluated and any of its fields are non zero. Added iterator functions test for a not_true computed field. Changed unselect to be like select and removed the redunant selected option from both gfx_select and gfx_unselect.
