Detailed Description

Implementation of the PNeXus class - NeXus HDF4/HDF5 file reader and writer.

This file contains the implementation of the PNeXus class for reading and writing ISIS muon NeXus HDF5 files. It provides case-insensitive path lookup functionality using the HDF4 C / HDF5 C++ API.

The implementation includes:

Read Functionality:

String utilities for case-insensitive comparison
Path parsing for HDF4 / HDF5 hierarchical paths
Recursive path traversal with case-insensitive matching
Attribute, group, and dataset lookup functions
Support for IDF version 1 and 2

Write Functionality:

Group hierarchy creation
Dataset writing for int, float, and string types
Attribute preservation
Multi-dimensional array support
Type-safe operations using PNXdata template class

Error Handling:

Comprehensive error handling with descriptive exceptions
Validation of data consistency
HDF4 error propagation / HDF5 exception propagation
