/* Document-method: default_options()
* call-seq: default_options()
*
* Returns the default load and dump options as a Hash. The options are
* - *:indent* [_Fixnum_|_String_|_nil_] number of spaces to indent each element in an JSON
*document, zero or nil is no newline between JSON elements, negative indicates no newline between
*top level JSON elements in a stream, a String indicates the string should be used for indentation
* - *:circular* [_Boolean_|_nil_] support circular references while dumping as well as shared
*references
* - *:auto_define* [_Boolean_|_nil_] automatically define classes if they do not exist

/* 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 indentation.
* - :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.
* - *:compat_bigdecimal* [_true_|_false_] load decimals as BigDecimal instead of as a Float in
*compat mode.
* - *: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_format* [_String_] the C printf format string for printing floats. Default follows
* the float_precision and will be changed if float_precision is changed. The string can be no more than 6 bytes.
* - *:float_precision* [_Fixnum_|_nil_] number of digits of precision when dumping floats, 0

*true (allow).

* - *: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.
* - *:ignore* [_nil_|Array] either nil or an Array of classes to ignore when dumping
* - *:ignore_under* [_Boolean_] if true then attributes that start with _ are ignored when
*dumping in object or custom mode.
* - *:cache_keys* [_Boolean_] if true then hash keys are cached
* - *:cache_str* [_Fixnum_] maximum string value length to cache (strings less than this are cached)
* - *:integer_range* [_Range_] Dump integers outside range as strings.
* - *:trace* [_Boolean_] turn trace on or off.
