%description
Quickly run experiments to compare the run time and output of code blocks.
The function mbc() can make fast comparisons of code, and will calculate
statistics comparing the resulting outputs. It can be used to compare
model fits to the same data or see which function runs faster. The R6
class ffexp$new() runs a function using all possible combinations of
selected inputs. This is useful for comparing the effect of different
parameter values. It can also run in parallel and automatically save
intermediate results, which is very useful for long computations.
