This change removes the Segment class as this takes forever to remove
from the segment array when removing low-priority segments. It has
instead been replaced by a wrapper function that works the same and
returns a working dict of all segment properties.
The regex substitution bottleneck in the vim example has been fixed by
using a single-character percent placeholder in vim segments which is
later replaced with a double percent using str.replace().
The examples have been moved into their own directory. The vim example
now uses pyeval() and vim.bindeval() and loads the Python file through
an import (so it gets compiled) for speed improvements.
