2011-02-02 : fixed a memory issue in the Python API for get_variable_attribute and has_variable_attribute

2011-01-25 : cannot set global attribute if it is an attribute that can be set via cmor_dataset
2011-01-25 : cannot set var attribute after var has been created into nc file
2011-01-25 : cannot set var attribute if it is settable via cmor_variable
2011-01-25 : can handle "character type" singleton dimensions
2011-01-25 : does not stores units on character typevariables
2011-01-24 : cmor_axes, interval check cleanup errormessage, now specifies which units the diff calaculated is in.
2011-01-24 : updated cmor_set_variable_attrubtes to go thru an 'internal' one

2010-12-16 : added two python test for var with string dimensions

2010-11-11 : new examples into Makefile for Python
2010-11-11 : added a flag that says need to cal cmor_grid on some axis (site and location)

2010-11-05 : removed option, for now, to create non-standard calendars because the dates in filenames would be wrong.

2010-11-05 : reverted ext_cell_measures to cell_measures

2010-10-27 : edited the test for permission on output directory, used to fail if you had group write privileges but that wasnt your main group

2010-10-22 : exposed cmor_set/get/has_variable in Fortran interface, just like Python works only on "string" variables
2010-10-22 : add optional "parent_experiment_rip" to cmor_dataset (C,Fortran,Python)
2010-10-22 : fixed bug with variables using "grids" and singleton dimensions
2010-10-22 : upgraded to 2.4 in devel branch
2010-10-22 : exposed cmor_set_variable_attribute to users in Python
2010-10-22 : cell_measures var attribute is now called ext_cell_measures

2010-10-22 : upgraded to 2.4 in devel branch
2010-10-22 : exposed cmor_set_variable_attribute to users in Python
2010-10-22 : cell_measures var attribute is now called ext_cell_measures

Merge branch 'master' into devel

2010-09-29 : Cleaned up error messages, now tries to output var/axis it was working on as well as table used.
2010-09-29 : When value that exceeds valid_min/max is found, now returns location of extreme point instead of first point encountered, as well as actuall coordinates values (not just indices)
2010-09-22 : Joerg found a bug that was due to checking only the refvar.dimension w/o checking the actual tables as well
2010-09-01 : fixed a bug on mac 32bit when reading in net3 version string
2010-09-01 : some vars with grid and singleton dims were wrongly analyzed by cmor_variable has not being defined with the right number of dimmensions.
2010-09-01 : updated doc. Was saying you can pass "none" for units when it really is: ""
2010-09-01 : updated doc. Was wrongly stating you can pass "none" if no missing_value
2010-08-24 : when writing time only variables, the time_bnds would fail to write if passed at cmor_write time.

2010-09-29 : Cleaned up error messages, now tries to output var/axis it was working on as well as table used.
2010-09-29 : When value that exceeds valid_min/max is found, now returns location of extreme point instead of first point encountered, as well as actuall coordinates values (not just indices)

Fixed Joerg's bug, had to do with checking only for the refvar dimension w/o also checking it's coming from the right table
