(fix) H5Z_xform_create function and scientific notation (#144)

Browse Source 
* (fix) H5Z_xform_create function and scientific notation

Implemented a more sophisticated check to support scientific notation
in the expression of the H5Zset_data_transform function.

* (fix) H5Z_xform_create and scientific notation: Added test.

Added a test to demonstrate that the parsing of expression
which includes scientific notation works correctly. Improved
inline comment.
