Description

The current storage type (in MatrixWorkspace) for masked bins:

typedef std::set< std::pair<int,double> > MaskList;

doesn't allow searching on bin index. std::map<int, double> would

Russell, can you give me your opinion on this?

I agree with this change. This came up when I suggested to Steve that he could make his new Qxy code simpler by using a find method. He then pointed out that he couldn't because the storage was a set of pairs.

I guess that there wasn't a use case for finding if a bin was masked in this manner when I first wrote the masking code. Should be a fairly simple change to implement and performance change should be close to zero (the internal storage will be essentially the same).

Refs #2053. Change internal storage type for masked bins.

The stored structure should be similar but the map lookup will be faster.
