NAME: NET_ENUMNODE
SYNOPSIS: Base class for SHARE,USE and SERVER EnumNode
INTERFACE:
NET_ENUMNODE() - constructor
GetInfo() - initialize the enum within the child class
GetNetResource() - get the NETRESOURCE data structure
IsFirstGetInfo() - check whether it is the first time to call
WNetResourceEnum().
SetGetInfo() - set the first ime flag to FALSE
PackString() - put the string in the end of the buffer
QueryType() - return the node type
QueryScope() - return the scope
QueryUsage() - return the usage of the node
QueryNetResource() - return the net resource pointer
PARENT: BASE
USES: LPNETRESOURCE
CAVEATS:
Base class for SHARE_ENUMNODE, USE_ENUMNODE and

are very fast (either an array lookup or table search).
