Instead of allocating new dictionaries for the scope elements, the scope
checks are just unrolled in-place. Now we have 6 almost identical methods
that differ only in the inline-check-method. Not optimal but minimal
memory and performance penalty.
This should reduce memory consumption and increase the performance
while parsing, see issue #10
Do not use the `allObjects` call on the reverse enumerators in the Parser
and the List of Active Formatting Elements to prevent allocating a new
array of the unenumerated objects.
This should reduce memory consumption while parsing, see issue #10
The data property is longer exposed as a mutable string. Instead all
manipulations must be performed via the provided API in order to ensure
correct updates for the Document’s attached ranges.
