Enhance code to read dimension scale data from an ASCII file
Previously, the tool only supports reading the dimension scale values from an ASCII file that holds the format 'one number per line'. While testing OMI and TES data, I found that some of their dimension scale data are stored in an attribute. HDFView shows the attribute values with commas. For users to conveniently copy the dimension scale data to an ASCII file,the tool had better support the reading of dimension scale data with common separator such as comma, white space and tab. This check-in adds this feature. It also uses a smaller buffer in case the dimension scale data is huge.
