Computes context that should be used to highlight and navigate matching braces

Parameters:

offset - offset we are computing for. Some implementations may need to compute this not only for caret position, but for other offsets, e.g. skipping spaces behind or ahead.

Returns:

a context should be used or null if there is no matching braces at offset
