Build the tree of validators and a SchemaDefinitions object from a JSON Schema.
The SchemaParser is an implementation of JsonParserInterface. As the JsonLexer encounters each token, it calls the appropriate method on the SchemaParser. The SchemaParser maintains a stack of contexts, each of which corresponds to a different part of the JSON schema. As objects / arrays are opened / closed, new contexts are added / removed from the context stack.

Called when a double value is encountered.
MinGW struggles with long doubles http://mingw.5.n7.nabble.com/Strange-behaviour-of-gcc-4-8-1-with-long-double-td32949.html To avoid this, and to keep as many significant bits as possible we keep the components of a double separate. See JsonDouble for details.
Implements ola::web::JsonParserInterface.

Called when a new key is encountered.
This may be called multiple times for the same object. The standard doesn't specify how to handle duplicate keys, so I generally use the last one.
Implements ola::web::JsonParserInterface.

Called when a string is encountered.
This is not called for object keys, see ObjectKey() below.
