Prefer simplejson over json
Introduced new schema with one function for all methods in class.
Instead of implementing all API's calls in dedicated functions,
one function will call API's method. So don't need write function for each API function.
Used only in item API
fixed result not returned in item calls
fixed list instead of dictionary in opts in API item
added new universal method in API Host
chaned all ZabbixAPI classes to new style
remove unused class systemmap
pep8 compliant
initial support of python3
__getattr__ moved to parent class
use ZabbixAPISubClass with parameters instead inheritance
cleanup and PEP8 complaint
add apiinfo method
add new methods from zabbix 2
added workaround for import function in configuration method.
add setup.py and .gitignore
