Implement CESR data types

[DmitryKuzmenko]

The scope of this task is the following: according to the list of supported primitive data types described in CESR draft:

• categorize the priorities of the data types we need to support;
• create a particular issue either for implementation of each one or unified by classes;
• implement each one.
