[Libroadrunner-devel] new beta

[Andy S. <and...@gm...>]

New beta is up, beta 7 (just Linux now, will get a Windows one in the morning). This build adds enhancements to event handling with variable time steps, some general improvements and specifically adds output points on each side of the event boundary separated by 1 machine epsilon. 

Some examples of the updated behavior are attached. The top plot is the before behavior, below is new. 

Note, this only works with variable time stepping, the fixed time steps will always produce a result like the top plot, as by definition it is on a fixed time points. 

Note, with variable time stepping, it is easy to skip over events, make sure you are setting your SimulateOptions.maximumTimeStep to a sane value to avoid too long time steps that might miss event triggers.
