 */

/*
 *  JSON_DEBUG is used to perform extra error checking.  Because libjson usually 
 *  does on the fly parsing, validation is impossible, so this option will allow
 *  you to register an error callback so that you can record what is going wrong 
 *  before the library crashes.  This option does not protect from these errors,
 *  it simply tells you about them, which is nice for debugging, but not preferable
 *  for release candidates
 */
//#define JSON_DEBUG


/*
 *  JSON_ISO_STRICT turns off all code that uses non-standard C++.  This removes all
 *  references to long long and long double as well as a few others
 */

/*
 *  JSON_SAFE performs similarly to JSON_DEBUG, except this option does protect
 *  from the errors that it encounters.  This option is recommended for those who
 *  feel it's possible for their program to encounter invalid json.
 */

/*
 *  JSON_STDERROR routes error messages to cerr instead of a callback, this

 *  messages in the console

/*
 *  JSON_PREPARSE causes all parsing to be done immediately.  By default, libjson
 *  parses nodes on the fly as they are needed, this makes parsing much faster if
 *  your program gets a lot of information that it doesn't need.  An example of
 *  this would be a client application communicating with a server if the server
 *  returns things like last modified date and other things that you don't use.
 */

/*
 *  JSON_LESS_MEMORY will force libjson to let go of memory as quickly as it can
 *  this is recommended for software that has to run on less than optimal machines.
 *  It will cut libjson's memory usage by about 20%, but also run slightly slower.
 *  It's recommended that you also compile using the -Os option, as this will also
 *  reduce the size of the library
 */

/*
 *  JSON_UNICODE tells libjson to use wstrings instead of regular strings, this
 *  means that libjson supports the full array of unicode characters, but also takes
 *  much more memory and processing power.

 *  JSON_REF_COUNT causes libjson to reference count JSONNodes, which makes copying
 *  and passing them around much faster.  It is recommended that this stay on for

/*
 *  JSON_MEMORY_CALLBACKS exposes functions to register callbacks for allocating, resizing,
 *  and freeing memory.  Because libjson is designed for customizability, it is feasible
 *  that some users would like to further add speed by having the library utilize a memory
 *  pool.  With this option turned on, the default behavior is still done internally unless
 *  a callback is registered.  So you can have this option on and not use it.
 */

 *  up memory that has been allocated by the user.  This includes strings, binary data, and
 *  nodes.  It also exposes bulk delete functions.
 */
//#define JSON_MEMORY_MANAGE


/*
 *	JSON_MEMORY_POOL Turns on libjson's iteraction with mempool++.  It is more efficient that simply
 *	connecting mempool++ to the callbacks because it integrates things internally and uses a number
 *	of memory pools.  This value tells libjson how large of a memory pool to start out with.  500KB 
 *	should suffice for most cases.  libjson will distribute that within the pool for the best
 *	performance depending on other settings.
 */
//#define JSON_MEMORY_POOL 524288


/*
 *  JSON_MUTEX_CALLBACKS exposes functions to register callbacks to lock and unlock
 *  mutexs and functions to lock and unlock JSONNodes and all of it's children.  This 
 *  does not prevent other threads from accessing the node, but will prevent them from
 *  locking it. It is much easier for the end programmer to allow libjson to manage
 *  your mutexs because of reference counting and manipulating trees, libjson automatically
 *  tracks mutex controls for you, so you only ever lock what you need to
 */
//#define JSON_MUTEX_CALLBACKS


/*
 *  JSON_MUTEX_MANAGE lets you set mutexes and forget them, libjson will not only keep
 *  track of the mutex, but also keep a count of how many nodes are using it, and delete
 *  it when there are no more references
 */
//#define JSON_MUTEX_MANAGE


/*
 *  JSON_NO_C_CONSTS removes consts from the C interface.  It still acts the same way, but
 *  this may be useful for using the header with languages or variants that don't have const

/*
 *  JSON_OCTAL allows libjson to use octal values in numbers.

 *  JSON_WRITE_PRIORITY turns on libjson's writing capabilties.  Without this libjson can only

 */

/*
 *  JSON_COMMENTS tells libjson to store and write comments.  libjson always supports

/*
 *  JSON_WRITE_BASH_COMMENTS will cause libjson to write all comments in bash (#) style

/*
 *  JSON_WRITE_SINGLE_LINE_COMMENTS will cause libjson to write all comments in using //

 */
//#define JSON_WRITE_SINGLE_LINE_COMMENTS


/*

/*
 *  JSON_BOOL_TYPE lets you change the bool type for the C interface.  Because before C99 there

/*
 *  JSON_STRING_HEADER allows you to change the type of string that libjson uses both for the

 */
//#define JSON_STRING_HEADER "../TestSuite/StringTest.h"


/*
 *  JSON_UNIT_TEST is used to maintain and debug the libjson.  It makes all private

 *  of libjson.  This should not be turned on by end users.

/*
 *  JSON_CASTABLE allows you to call as_bool on a number and have it do the 0 or not 0 check,
