This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.

Since m_pos is passed into GetAt() on the underlying string in
getCurrentChar(), the value of it needs to confirmed to be valid after
decrementing. Some types were changed to reflect the values being
stored.

The various string/byte classes support Mid(), Left(), and Right() for
extracting substrings. Mid() can handle all possible cases, but Left()
and Right() are useful for common cases and more explicit about what
is going on.
Calls like Mid(offset, length - offset) can be converted to
Right(length - offset). Calls like Mid(0, length) can be converted to
Left(length).
If the substring being extracted does not extend all the way to one of
the edges of the string, then Mid() still needs to be used.
