Fix issue 844/848.

Fixing issue 859.

Add test cases for the event handler for schema tags; does not include test cases for Node because specialized tag handling is not implemented yet.

E.g. `!2`.

Specifically, printing `.nan`, `.inf`, and `-.inf`, respectively, as per the spec section 10.2.1.4.

Invalid access via operator[] or as<> will now print the offending key, if possible.

For example:

a:
  x: 1
  y: 2

node["a"]["z"].as<int>()

will say that the key "z" was invalid.

ref #110

The issue is that numbers like
2.01 or 3.01 can not be precisely represented with binary floating point
numbers.

This replaces all occurrences of 'std::numeric_limits<T>::digits10 + 1' with
'std::numeric_limits<T>::max_digits10'.

Background:
Using 'std::numeric_limits<T>::digits10 + 1' is not precise enough.
Converting a 'float' into a 'string' and back to a 'float' will not always
produce the original 'float' value. To guarantee that the 'string'
representation has sufficient precision the value
'std::numeric_limits<T>::max_digits10' has to be used.

* Skip newlines in binary decoding
This fixes #387

* Skip all whitespace characters

This also removes spaces and tabs in addition to newlines.

Add EmitterStyle, which will allow sequence or map style (i.e., flow or block) to be preserved between parsing and emitting
