New features

Manually specify minimum and maximum range of the plots in the data logger. Overrides autoscale.
Added a stopwatch Widget to the Newton's Law of Cooling Experiment under the Thermal Physics Section for manually recording temperature data vs time.

Added a visual code example for recording and plotting data from pH meters.

Slope and offset value for Volt to pH conversion is editable, and default values are prefilled based on a cheap portable meter used in agriculture.
