v1.4

Added a feature to find transitions between siteswap patterns, available as the new "Transitions" tab. Also added the ability to copy patterns out of pattern lists, and made various bug fixes to the siteswap generator and parsing code.

v1.3

Added optimizer feature, available as the File-->Optimize menu item on each animation window. The optimizer adjusts the throwing and catching positions in the pattern so as to maximize the margin of throwing error. Here the margin of throwing error is defined in an angular sense: It is defined as the largest angle such that, if all throws are within this amount of the ideal throw angle(s), then no collisions will occur in the pattern.

v1.2

change version to 1.2
