^ remove a component from ui
^ component: component to delete

ui.set_default(name)
^ set component to show if not a single component is set visible
^ name: name of component to set as default

ui.find_by_name(name) --> returns component or nil
^ find a component within ui
^ name: name of component to look for

File: fst/tabview.lua
---------------------

tabview_create(name, size, tabheaderpos) --> returns tabview component
^ create a new tabview component
^ name: name of tabview (has to be unique per ui)
^ size: size of tabview
	{
		x,
		y
	}
^ tabheaderpos: upper left position of tabheader (relative to upper left fs corner)
	{
		x,
		y
	}

Class reference tabview:

methods:
- add_tab(tab)
  ^ add a tab to this tabview
  ^ tab:

	caption            = "tab caption",  -- text to show for tab header
	cbf_button_handler = function(tabview, fields, tabname, tabdata), -- callback for button events
	--TODO cbf_events         = function(tabview, event, tabname),           -- callback for events
	cbf_formspec       = function(tabview, name, tabdata),            -- get formspec
	tabsize            =
		{
			x, -- x width
			y  -- y height
		},                                                            -- special size for this tab (only relevant if no parent for tabview set)

  ^ set a handler to be called prior calling tab specific button handler
  ^ handler: function(tabview,fields) --> returns true to finish button processing false to continue

Skeleton for any component:
{
	name           = "some id",               -- unique id

	                                          -- addon:    component is an addon to be shown along toplevel component
	hide           = function(this) end,      -- called to hide the component
	show           = function(this) end,      -- called to show the component
	delete         = function(this) end,      -- called to delete component from ui
	handle_buttons = function(this,fields)    -- called upon button press
	handle_events  = function(this,event)     -- called upon event reception
	get_formspec   = function(this)           -- has to return formspec to be displayed
