Message:

Refactored Cansas HDF5 reader to allow multiple instances of SASdata of any dimensionality in a single SASentry and multiple instances of SASentry in a single file. Added unit tests to test all types of data (1 entry | 1 data, 1 entry | many data, many entry | 1 data each, many entr |, many data).

Location:

test/sasdataloader/test

Files:

• cansas_1Dand2D_multiplesasentry_multiplesasdata.h5 (added)
• cansas_1Dand2D_samedatafile.h5 (added)
• cansas_1Dand2D_samesasentry.h5 (added)
• simpleexamplefile.h5 (added)
• utest_cansas.py (modified) (17 diffs)
