exposing python to method for converting between SpecNum, WI and detID

[Anders Markvardsen]

MatrixWorkspace class has various method for converting between SpecNum, WI and detID including:

size_t getIndexFromSpectrumNumber (const specid_t specNo) const

Given a spectrum number, find the corresponding workspace index.

void getIndicesFromDetectorIDs (const std::vector< detid_t > &detIdList, std::vector< size_t > &indexList) const

Converts a list of detector IDs to the corresponding workspace indices.

void getIndicesFromSpectra (const std::vector< specid_t > &spectraList, std::vector< size_t > &indexList) const

Converts a list of spectrum numbers to the corresponding workspace indices.

virtual void getIntegratedSpectra (std::vector< double > &out, const double minX, const double maxX, const bool entireRange) const

Return a vector with the integrated counts for all spectra withing the given range.

spec2index_map * getSpectrumToWorkspaceIndexMap () const

Return a map where: KEY is the Spectrum # VALUE is the Workspace Index.

void getSpectrumToWorkspaceIndexVector (std::vector< size_t > &out, specid_t &offset) const

Return a vector where: The index into the vector = spectrum number + offset The value at that index = the corresponding Workspace Index.

index2detid_map * getWorkspaceIndexToDetectorIDMap () const

Return a map where: KEY is the Workspace Index VALUE is the DetectorID (pixel ID).

index2spec_map * getWorkspaceIndexToSpectrumMap () const

Return a map where: KEY is the Workspace Index VALUE is the Spectrum #.

Some of these method are not in a 'convenient' (not 100% sure if this is the right work for it) state to be exposed to python.

Purpose of this ticket is to expose some C++ methods to python which allow for the convertion between SpecNum, WI and detID
