== 0.0.5
- support self-define width of sectors when initializing sectors
- add simple functions to read and manuplate cytoband file
- add several new figures in the vignettes and vignettes have been improved.
- ``cell.padding`` in `circos.par` now using degree as its measurement.
- ``track.margin`` in `circos.par` now using percentage of radius as its measurement.

== 0.0.4
- number of points to simulate quadratic curves decreased
- labels on axis in `circos.initializeWithIdeogram` is now 'vertical_right' by default

- start degree and end degree now consistent with the data axis.
- the first sector is drawn first now.
- add `draw.sector`

== 0.0.2
- add `draw.sector` so it would be more straightforward to highlight sectors
