0023850: TDataStd_ByteArray is too slow on storage on disk

Browse Source 
Optimization of a byte-array for XML persistence (binary persistence is ok).
A possible bug is corrected (size of an array is extended a little).
Same improvement for storage of a TDataStd_TreeNode.
Improvement of speed of storage of several Ocaf attributes in XML file format.
Also, format of storage of a double value is extended to keep 17 digits after a decimal point (it was used only 15 digits before).
Several draw-commands are added to manipulate the basic Ocaf attributes:
BooleanArray
BooleanList
IntegerList
RealList
A test-script for OCAF document successfully saved and opened from disk in XML file format.
+ 1 is added to keep '\0'
Removed several spaces in source files.
PLib_LocalArray is renamed to NCollection_LocalArray and became a template. It is used as a local array for Standard_Character in XML OCAF drivers, and as a local array of Standard_Real in PLib package.
Small correction of test case for this fix
