This file contains the definition for the MASK_MAP class.
A MASK_MAP is a BITFIELD, NLS_STR pair that can be used to
associate bitmasks with strings.

SYNOPSIS: This structure can be used for static initialization
that is compatible with MASK_MAP::Add.
CAVEATS:
NOTES: usBitMask is the initialized bitfield
idsStringID is the ID of the string that will be loaded
with NLS_STR::LoadString
nID is the app defined ID of this pair.

SYNOPSIS: This is a container class for the MASK_MAP class.
INTERFACE: QueryString & QueryBitfield, returns the string and

the user defined ID associated with the string and bitset.

/*************************************************************************
NAME: MASK_MAP
SYNOPSIS: This class provides a bitfield/string lookup table that
optionally allows a user defined classification (by using
an int ID key value that is used for lookups).
INTERFACE:
Add
Adds an association to the list with the specified
bitfield, string and id.
Add (alternate form)
Adds an array of struct US_IDS_PAIRS, good for static
initialization.
BitsToString, StringToBits
Finds the first matching passed String/Bitfield with the requested
ID and returns the corresponding Bitfield/string.
EnumStrings, EnumBits
Lists all of the strings in the class or all of the bits in
the class (respectively) that have the ID that matches the
passed ID. pfFromBeginning indicates start from the beginning
of the list, it will be set to FALSE automatically. While the
method returns TRUE, there is more data.
IsPresent
Searches for a particular bitfield and returns TRUE if found
QueryBits
Retrieves the nth bitfield and string in this maskmap
PARENT: BASE
USES: BITFIELD, NLS_STR
CAVEATS:
NOTES: As a CODEWORK item, may want to allow a search value of -1 for
the ID which means accept any ID (this might be useful for
BitsToString/StringToBits and the Enum* methods.

StringToBits and BitsToString
