The grab function would find the index of the first occurrence of the
"start" string in the parent string and then the next occurrence of the
"end" string starting from that index and return the substring between
those.
So in the example:
sample = "sqrt(sin(x) + cos(y))"
The grab function would return:
sample.grab(start="sqrt(", end=")")
>> "sin(x"
This shows that "grab" is only useful given that you specify the "start"
and "end" delimiters unambiguously. It depends on that to produce the
correct output.
