Class property documentation, replace ‘std’ with ‘default’ (while maintaining back-compat), esc_textarea for textareas, remove cmb_Meta_Box_Validate (for now), and make sure ‘cmb_show_on’ filter is applied on the display side as well.

move cmb_Meta_Box_Validate to it’s own file, make  a class method, introduce 'sanitization_cb' field parameter, explicitly set the  field property, move sanitization methods to cmb_Meta_Box_Validate, and send sanitization through cmb_Meta_Box::sanitization_cb().
whitespace differences
cmb_Meta_Box_Show_Filters::check_id now more accurately gets the ID on the front-end
remove repeatable variables/methods, in favor of explicitly set 'repeatable' field parameter, and use  in all methods
