4.7.5

• Added in a BchronCheck function to allow for checking of all argument types using checkmate
• Added in positionEps argument to Bchronology to avoid positions being simulated too close to each other and leading to numerical underflow errors
• Changed default colours of dates in plot.CalibratedDates and plot.BchronologyRun
• Added an extra check that all ageSds are bigger than zero
• Allowed the option for calibrating dates out of calibration curve range
• Fixed bug that occurred with large 14C values close to upper range of calibration curve
• Changed the means by which starting values are created. This was to fix a bug (issue #17 on GitHub) where a middle extreme date (e.g. non-14C) could cause the starting values of the stratigraphically ordered dates to fall beyond the range of the calibration curve.
• Included option to allow bespoke starting values for complex cores
• Changed some of the algorithm details to avoid certain bugs with numerical underflow problems (tested in test_all_chrons)
