Alignment

1) create straw centers along the x axis, 
 with inner most straw at x=0, direction pointing along +y
1a) apply panel alignment rotation in this basis
as a right-handed rotation about x, then y, then z
from db delta values du, dv, dw
where u=x, v=y, w=z.  using u,v,w empahsizes that
these are not the experiment coordinates for the panel
1b) apply panel alignment postion, in this basis
 using db values du dv and dw
2) apply the nominal geometry transformaton to put
  the panel in the plane: push it out the x axis, tweak the z,
  rotate about the z axis.
2a) apply the panel alignment rotion in this basis
from db delta values rx, ry, rz
2b) apply the panel offset in this basis
from db delta values dx, dy, dz
3) apply the nominal transformation to place the
 plane in the tracker - shift along z
2a) apply the detector alignment rotion in this basis
from db delta values rx, ry, rz
2b) apply the detector offset in this basis
from db delta values dx, dy, dz
