Compound data, file size and fixed length strings

[cmccarthy1]

• Addition of functionality to handle compound datasets containing supported types

  // From root of directory
  $q hdf5.q
  q).hdf5.readData["testdata/ex_table_02.h5";"table"]
  Name    Latitude Longitude Pressure Temperature
  -----------------------------------------------
  "zero"  0        0         0        0          
  "one"   10       10        1        10

  "eight" 80       80        8        80         
  "nine"  90       90        9        90         

• Addition of function to check the size of a file in MB
• .hdf5.readChar can now read fixed length string messages (previously only variable length strings could be read)
• Addition of folder to hold some example datasets (currently only for the compound dataset but may be extendable to compressed data etc.)
