BullScript bracket matching

   Much of the power of BullScript (and most scripting languages) comes
from the ability to be able to use the results of one function as the
input of another. Ie, putting one function inside another. This is
called nesting. 

However, nesting can quickly cause a script to become difficult to
read, as you can end up with many levels of brackets. The BullScript
editor has a bracket matching feature to make it easier to read nested scripts.

When viewing a script, place the cursor just before
an opening bracket. The bracket will become pink (or red in ver 2.4.1
or older), and the corresponding closing bracket will also become pink.
Alternatively you can place the cursor after the closing bracket to see the starting bracket.

In the example above, the cursor has been placed just after the "if".
Notice that the following bracket and the corresponding closing bracket
are highlighted.

If the brackets belong to a function, and that function has several
parameters, then the commas are also highlighted. This makes it easier
to identify what script is being used for each of the parameters.

By looking at the highlighted brackets and commas in the example above, it can be more easily seen that:

  V < hist(V,1)   is the condition of the "if" function.
  Previous(1000) + (((expr - hist(expr,1)) / hist(expr,1))*Previous(1000))  is the script used if the condition is true.
  Previous(1000) is the script used if the condition is false.
