Updated handling of '\b' when inside character class, made invalid
...
escapes an error.
The '\b' value refers to a word boundary normally, but refers to the
backspace ASCII value inside a character class. I updated
newEscapedNode() to deal with this. I also changed the behavior, so that
trying to escape any other value results in an error, instead of just
returning the character as-is.

Changed the value of EPSILON, so that we can use the NUL character
...
(which it used to be) in a regex; Also added code to detect escaped
backslashes
Specifically, I replace an escaped backslash with a metacharacter, then
replace it back later on. This prevents problems, like detecting whether
the opening bracket is escaped in '\\[a]'.
