/* Document-method: default_options=

*
* Sets the default options for load and dump.
* - *opts* [_Hash_] options to change
* - *:indent* [_Fixnum_|_String_|_nil_] number of spaces to indent each element in a JSON document or the String to use for identation.
* - :circular [_Boolean_|_nil_] support circular references while dumping.
* - *:auto_define* [_Boolean_|_nil_] automatically define classes if they do not exist.
* - *:symbol_keys* [_Boolean_|_nil_] convert hash keys to symbols.
* - *:class_cache* [_Boolean_|_nil_] cache classes for faster parsing.
* - *:escape* [_:newline_|_:json_|_:xss_safe_|_:ascii_|_unicode_xss_|_nil_] mode encodes all high-bit characters as escaped sequences if :ascii, :json is standand UTF-8 JSON encoding, :newline is the same as :json but newlines are not escaped, :unicode_xss allows unicode but escapes &, <, and >, and any \u20xx characters along with some others, and :xss_safe escapes &, <, and >, and some others.
* - *:bigdecimal_as_decimal* [_Boolean_|_nil_] dump BigDecimal as a decimal number or as a String.
* - *:bigdecimal_load* [_:bigdecimal_|_:float_|_:auto_|_nil_] load decimals as BigDecimal instead of as a Float. :auto pick the most precise for the number of digits.
* - *:mode* [_:object_|_:strict_|_:compat_|_:null_|_:custom_|_:rails_|_:wab_] load and dump mode to use for JSON :strict raises an exception when a non-supported Object is encountered. :compat attempts to extract variable values from an Object using to_json() or to_hash() then it walks the Object's variables if neither is found. The :object mode ignores to_hash() and to_json() methods and encodes variables using code internal to the Oj gem. The :null mode ignores non-supported Objects and replaces them with a null. The :custom mode honors all dump options. The :rails more mimics rails and Active behavior.
* - *:time_format* [_:unix_|_:xmlschema_|_:ruby_] time format when dumping in :compat mode :unix decimal number denoting the number of seconds since 1/1/1970, :unix_zone decimal number denoting the number of seconds since 1/1/1970 plus the utc_offset in the exponent, :xmlschema date-time format taken from XML Schema as a String, :ruby Time.to_s formatted String.
* - *:create_id* [_String_|_nil_] create id for json compatible object encoding
* - *:create_additions* [_Boolean_|_nil_] if true allow creation of instances using create_id on load.
* - *:second_precision* [_Fixnum_|_nil_] number of digits after the decimal when dumping the seconds portion of time.
* - *:float_precision* [_Fixnum_|_nil_] number of digits of precision when dumping floats, 0 indicates use Ruby.
* - *:use_to_json* [_Boolean_|_nil_] call to_json() methods on dump, default is false.
* - *:use_as_json* [_Boolean_|_nil_] call as_json() methods on dump, default is false.
* - *:use_to_hash* [_Boolean_|_nil_] call to_hash() methods on dump, default is false.
* - *:nilnil* [_Boolean_|_nil_] if true a nil input to load will return nil and not raise an Exception.

* - *:space* [_String_|_nil_] String to use for the space after the colon in JSON object fields.
* - *:space_before* [_String_|_nil_] String to use before the colon separator in JSON object fields.
* - *:object_nl* [_String_|_nil_] String to use after a JSON object field value.
* - *:array_nl* [_String_|_nil_] String to use after a JSON array value
* - *:nan* [_:null_|_:huge_|_:word_|_:raise_] how to dump Infinity and NaN in null, strict, and compat mode. :null places a null, :huge places a huge number, :word places Infinity or NaN, :raise raises and exception, :auto uses default for each mode.
* - *:hash_class* [_Class_|_nil_] Class to use instead of Hash on load, :object_class can also be used.
* - *:array_class* [_Class_|_nil_] Class to use instead of Array on load.
* - *:omit_nil* [_true_|_false_] if true Hash and Object attributes with nil values are omitted.
