*
* This unit is inspired from the json c lib:
* Michael Clark <michael@metaparadigm.com>
* http://oss.metaparadigm.com/json-c/
*
* CHANGES:
* v1.2
* + support of currency data type
* + right trim unquoted string
* + read Unicode Files and streams (Litle Endian with BOM)
* + Fix bug on javadate functions + windows nt compatibility
* + Now you can force to parse only the canonical syntax of JSON using the stric parameter
* + Delphi 2010 RTTI marshalling
* v1.1
* + Double licence MPL or LGPL.
* + Delphi 2009 compatibility & Unicode support.
* + AsString return a string instead of PChar.
* + Escaped and Unascaped JSON serialiser.
* + Missed FormFeed added \f
* - Removed @ trick, uses forcepath() method instead.
* + Fixed parse error with uppercase E symbol in numbers.
* + Fixed possible buffer overflow when enlarging array.
* + Added "delete", "pack", "insert" methods for arrays and/or objects
* + Multi parametters when calling methods
* + Delphi Enumerator (for obj1 in obj2 do ...)
* + Format method ex: obj.format('<%name%>%tab[1]%</%name%>')
* + ParseFile and ParseStream methods
* + Parser now understand hexdecimal c syntax ex: \xFF
* + Null Object Design Patern (ex: for obj in values.N['path'] do ...)
* v1.0
* + renamed class
* + interfaced object
* + added a new data type: the method
* + parser can now evaluate properties and call methods
* - removed obselet rpc class
* - removed "find" method, now you can use "parse" method instead
* v0.6
* + refactoring
* v0.5
* + new find method to get or set value using a path syntax
* ex: obj.s['obj.prop[1]'] := 'string value';
* obj.a['@obj.array'].b[n] := true; // @ -> create property if necessary
* v0.4
* + bug corrected: AVL tree badly balanced.
* v0.3
* + New validator partially based on the Kwalify syntax.
* + extended syntax to parse unquoted fields.
* + Freepascal compatibility win32/64 Linux32/64.
* + JavaToDelphiDateTime and DelphiToJavaDateTime improved for UTC.
* + new TJsonObject.Compare function.
* v0.2
* + Hashed string list replaced with a faster AVL tree
* + JsonInt data type can be changed to int64
* + JavaToDelphiDateTime and DelphiToJavaDateTime helper fonctions
* + from json-c v0.7
* + Add escaping of backslash to json output
* + Add escaping of foward slash on tokenizing and output
* + Changes to internal tokenizer from using recursion to
* using a depth state structure to allow incremental parsing
* v0.1
* + first release
