""" -----RELEASE LOG/NOTES/PONTIFICATIONS-----
v0.1.0 - 04.11.11
basic generate functions and UI
object creation report (Custom Properties: FSLG_REPORT)
v0.2.0 - 04.15.11
started spelling laplacian right.
add curve function (not in UI) ...twisting problem
classify stroke by MAIN path, h-ORDER paths, TIP paths
jitter cells for mesh creation
add materials if present
v0.2.1 - 04.16.11
mesh classification speedup
v0.2.2 - 04.21.11
fxns to write/read array to file
restrict growth to insulator cells (object bounding box)
origin/ground defineable by object
gridunit more like 'resolution'
v0.2.3 - 04.24.11
cloud attractor object (termintates loop if hit)
secondary path orders (hOrder) disabled in UI (set to 1)
v0.2.4 - 04.26.11
fixed object selection in UI
will not run if required object not selected
moved to view 3d > toolbox
v0.2.5 - 05.08.11
testing for 2.57b
single mesh output (for build modifier)
speedups (dist fxn)
v0.2.6 - 06.20.11
scale/pos on 'write to cubes' works now
if origin obj is mesh, uses all verts as initial charges
semi-helpful tooltips
speedups, faster dedupe fxn, faster classification
use any shape mesh obj as insulator mesh
must have rot=0, scale=1, origin set to geometry
often fails to block bolt with curved/complex shapes
separate single and multi mesh creation
v0.2.7 - 01.05.13
fixed the issue that prevented enabling the add-on
fixed makeMeshCube fxn
disabled visualization for voxels
v0.x -
-prevent create_setup_objects from generating duplicates
-fix vis fxn to only buildCPGraph once for VM or VS
-improve list fxns (rid of ((x,y,z),w) and use (x,y,z,w)), use 'sets'
-create python cmodule for a few of most costly fxns
i have pretty much no idea how to do this yet
-cloud and insulator can be groups of MESH objs
-text output, possibly to save on interrupt, allow continue from text
-?hook modifiers from tips->sides->main, weight w/ vert groups
-user defined 'attractor' path
-fix add curve function
-animated arcs via. ionization path
-environment map boundary conditions - requires Eqn. 15 from FSLG.
-assign wattage at each segment for HDRI
-?default settings for -lightning, -teslacoil, -spark/arc
-fix hOrder functionality
-multiple 'MAIN' brances for non-lightning discharges
-n-symmetry option, create mirror images, snowflakes, etc...
