2	Class that holds a fit page state
3
4	Pagestate fields reflect the names of the gui controls from the sasview 3.x
5	fit page, so they are somewhat difficult to interpret.
6
7	Pagestate attributes are as follows:
8
9	# =>name: desc indicates the attribute is derived
10	# name(xml): desc indicates the attribute name differs from the xml tag
11
12	# SasView version which saved the file
13	version: (4, 1, 2) from <fitting_plug_in version="major.minor.point">
14
15	# Session information
16	group_id: unique id for fit page in running system (int)
17	=> data_group_id: unique id for data item in running system (None)

23	file: filename + [date time] (latex_smeared.xml [Apr 09 15:45])
24	name: ?? (None)
25	npts: number of points (float)
26	enable2D: True if data is 2D (or if model is 2D and no data)

46	dq_l: 2D resolution <dQp>
47	dq_r: 2D resolution <dQs>

49	than dx_percent, with dx_percent interpreted as 100 * dx_percent/q[0]
