+Todos:
+    toolpath generating(using single bit):
+        toolpath of every net,toolpath of a total layer,toolpath collision check
+    tool library:
+        creating a bit,bit choosing
+    multiple bit toolpath generating(based on tool library)
+    DRC:
+        DRC at opening a gerber file(base on tool library)
+    Adding centering holes(horizontal/vertical/quadruple)
+    smart drill hole generating(need drill library)
+    Postprocessing:
+        Drill file output
+        topLayer output
+        bottomLayer output(mirror)
+        routing output
+
+    most of running time are dominated by intersect calculation,not data read/write/move

+---------------------------------gerberCAM v0.7---------------------------------
+add treeview
+add setting dialog,tool library
+add hole recognize,drawing
+todo:    tool select
+
+
+---------------------------------gerberCAM v0.65---------------------------------
+todo:improve geber instruction interpreting(G36,G37,AM,rotary...)
+fix drawPCB bug in v0.64
+
+
+---------------------------------gerberCAM v0.64---------------------------------
+todo:improve geber instruction interpreting(G36,G37,AM,rotary...)
+drawPCB.cpp:
+    when drawing a pad,using the original point as center point
+
+gerber.cpp:
+    use boundingRect to determine borderRect(to be tested)
+
+a bug in toolpath.cpp:can be found using ro5.gtl
+
+
+---------------------------------gerberCAM v0.63---------------------------------
+add threshold to define contours(calculating boundingRect area)
+paint contour
+paint the collided toolpath nets
+
+
+---------------------------------gerberCAM v0.62---------------------------------
+automatically recognize contour as a routing toolpath
+toolpath collision detect
+fix preprocess.cpp:
+    sameNet()--mergeRect() error
+    sameNet()--removeAt() error
+
+
+
+---------------------------------gerberCAM v0.61---------------------------------
+successfully generated the toolpath
+fix preprocess.cpp&toolpath.cpp:
+    fix the calculation error in trackToMyRect method
+
+
+
+---------------------------------gerberCAM v0.6---------------------------------
+replace all float data with integer
+speed is improved due to int type
+start using clipper library
+bug:
+    netList number is not the same as previous versions(now is less)
+        and this bug appears only on some gerberfiles(pcb3.gtl)
+
+
+---------------------------------gerberCAM v0.5---------------------------------
+    start to generate toolpath
+toolpath.cpp
+    generated toolpath of every single element
+
+
+
+---------------------------------gerberCAM v0.42---------------------------------
+add preprocess.cpp to handle gerber data first
+
+bug:
+    gerber.h:different order of variables in struct will cause corrupt
+    toolpath::sameNet():cant use g.padsList.at(i).block.boundingRect;
+
+
+mainwindow.cpp:
+    added coordinate display at statusbar
+    improve zoom in/out action
+
+preprocess.cpp:
+    move toolpath to preprocess.cpp
+    add boundingRect to every Net,largely reduce time!sepecially for 10k+ segments file
+toolpath.cpp:
+    adding bounding rect to reduce calculation
+
+fix toolpath.cpp:
+    fix a bug in net categorization
+    floating point data comparision error
+
+fix:
+    zoom in/out problem
+
+fix drawPCB.cpp:
+    fix boundingRect error,display normal now
+
+
+---------------------------------gerberCAM v0.3---------------------------------
+start to calculate toolpath
+toolpath.cpp
+    finished track&track collision detect
+    finished track&pad collision detect
+    finished pad&pad collision detect
+    finished net categorization
+
+fix gerber.cpp:
+    gerber trackNum count error
+    gerber borderRect error
+
+gerber.cpp:
+    add block count to reduce net calculation
+
+
+---------------------------------gerberCAM v0.2---------------------------------
+add a drawPCB class to take care of drawing layer
+Obround pad is drawn by a short line with roundcap instead of ellipse
+import 2 layers
+fit in view
+
+
+---------------------------------gerberCAM v0.1---------------------------------
+gerberfile: basic interpret
