	OpenMaya deprecation system

	Macros to allow code to be selectively removed from the build based on
	deprecation criteria.

	Here is a list of the currently supported deprecation flags. To build your
	plug-in to be compatible with deprecated functions removed just add the
	following defines to your compile flags:

	<ul>
		<li>OPENMAYA_DEPRECATION_DISABLE_WARNING		: Silence deprecation warnings</li>
	</ul>

	Defined attributes:
	<ul>
		<li>OPENMAYA_DEPRECATED(version, message)	: Methods and classes marked with this attributes are deprecated from "version", see "message" for replacement.
	</ul>

	Defined helper directives:
	<ul>
		<li>_OPENMAYA_DEPRECATION_PUSH_AND_DISABLE_WARNING	: Disable the deprecation warning until the _OPENMAYA_POP_WARNING directive </li>
		<li>_OPENMAYA_POP_WARNING				: Restore the deprecation warning </li>
	</ul>

	If you are building with a customized compiler that does not have a proper support
	it is safe to disable or edit this header file.

\brief Help on Open Maya deprecation system
## To treat deprecation as an error, use the following compiler switch:

- MSVC	: /We"4996" /D_CRT_NONSTDC_NO_DEPRECATE
- ICC	: -diag-error 1786
- Clang	: -Werror=deprecated-declarations
- GCC	: -Werror=deprecated-declarations

## To silence the deprecation warnings:

Define preprocessor macro
	_OPENMAYA_DEPRECATION_DISABLE_WARNING

Or use the following compiler switch:

- MSVC	: /Wd"4996"
- ICC	: -diag-disable 1786
- Clang	: -Wno-error=deprecated-declarations
- GCC	: -Wno-error=deprecated-declarations
