Elle Microstructural Modelling SVN Code

fft2elle:
update the cellbbox is passed 0,0,0 for xyz strain. Is this why U_ATTRIB_C
was necessary?
Try not using U_ATTRIB_C. If a unode changes flynn when bnodes and unodes
have been moved, remove it from the old flynn unode list then add it to the
new flynn and set its EULER_3 to the orientation of the nearest unode in
the new flynn

elle2fft
Initialise user data
[0] 256 (rows)
[1] 0 should be set so that sq_grid is false but unnecessary as code
changed to always use FindUnode(pos,start)
[2] 1 elle angles in degrees. Code that converted from radians to
degrees was wrong (*DTOR instead of *RTOD) but not used

FindUnode(pt,start)
Function has been moved to basecode (unodes.cc) and searches all the unodes
to find the closest to the pt
FindUnode_alb(pt,start) searched the unodelist of each flynn for
unode<dist_min from pt, where dist_min=10. If a unode was not found then it
searched all the
unodes ????
Unodes and fft pts being repositioned to a trapezoid but elle file has
already been through reposition. Changed to just use current unode positions.
Program was checking value of ElleSSOffset() but should check corners?

Fixed bug that stopped plotting of flynn boundaries over unode plots

ElleInitNodeAttribute() did not check whether the attribute was already
active. Multiple entries could occur in the attribute list.

added multiples of 90° rotation of bnodes option

fix crash on OnCloseWindow under windows

change save movie default to png as it gives better quality AND smaller images

modified how to select import variables (now using user values) and
change "print" commands to "log".

Check for case where unode is not in any element (rounding may put it
outside the mesh?). This could result in erroneous position calculations
so for now we will not change the position.
