                         MulticastAddressAllocator

This class provides a clean API for allocating multicast addresses. It can provide addresses either randomly from the predefined SDP pool or randomly from a pool provided by the user.

Method Summary
	`__init__(self, baseAddress, addressMaskSize, portBase)` We initialize this class with the information needed to allocate addresses.
	`AllocateAddress(self)`
	`GetAddressMask(self)`
	`GetBaseAddress(self)`
	`RecycleAddress(self, address)`
	`SetAddressMask(self, addressMaskSize)`
	`SetBaseAddress(self, baseAddress)`
Inherited from NetworkAddressAllocator
	`AllocatePort(self, even)` if the even flag is set we allocate only an even port to support RTP standard use cases.
	`AllocatePortInRange(self, even, portBase, portMax)`
	`GetAllocationMethod(self)`
	`RecyclePort(self, port)`
	`SetAllocationMethod(self, method)`
	`SetPortBase(self, portBase)`
	`SetPortMax(self, portMax)`

Class Variable Summary
`str`	`INTERVAL` = `'interval'`
`str`	`RANDOM` = `'random'`
`str`	`SDR_BASE_ADDRESS` = `'224.2.128.0'`
`int`	`SDR_MASK_SIZE` = 17

Method Details

init(self, baseAddress=None, addressMaskSize=24, portBase=49152)
(Constructor)

We initialize this class with the information needed to allocate addresses. A base address and address mask imply we're allocating from a GLOP address space. If a base address and mask are not supplied the allocator allocates from the SDR address space.
