== Livido Parameters ==

High level interface definition

A parameter is a mechanism that controls some aspect of the plugin.
Each parameter has a set of properties that identify the contraints
and behaviour of a parameter.

The Parameter component in Livido accesses its primitives trough
another layer (the middle layer).
The middle layer is not discussed here.

Parameters have:

 * A set of properties
 * A category
   * Transition
   * Color RGBA
   * Number
   * Tekst
   * ...
 * A flag
   * keyframeable
   * optional
   * ...


== Property ==

A property contains:

 * Key
 * payload 
 * flags

The key is used as a unique identifier for the propery. 
The payload is a datastructure from the middle layer.
The flags are used to set a property read-only or writeable.

Below follows an (incomplete?) list of all properties known in the component Parameter

 * (current) value
 * default
 * min
 * max
 * step size
 * page size
 * group id
 * enabled/disabled
