"""
Create a command line program with automatic parsing of actions
and parameters based on decorators.
This class define common methods for a command line interface
(CLI) program. You should extends it and add methods with specific
decorators to create personalized CLI programs.
This class defines a CLI program which accepts parameters (of any
kind) and do actions using those parameters. Only one action will
run for a given command line. if more than one action was asked,
only the first will run.
The general form of the arguments that CLI accepts is given
below:
cli-program (--action-1|--action-2|...|--action-n)
[--param-1=value1,--param-2=value-2|...|--param-n=value-n]
Al parameters are optional, action code will check for required
parameters and shout if needed.
At least one action is required, if none given, --help will be
fired.
There are a few auto-generated options:
--help --quiet --verbose (default=True) --log=file
To create actions, use 'action' decorator. If that action was
detected on the command line arguments, action method will be
called with an object containing all the parameters available.
For example:
@action(short='s', long='slew'):
def slew(self, options):
inst.slew(options.ra, options.dec)
To define parameters, use parameter decorator or addParameter method.
The parameter method passed to the decorator will be called to validate
the parameter value given on the command line. Otherwise, no
validation, besides type checking, will be done.
For example:
self.addParameter(name='ra', help='Help for RA', type=string)
or
@parameter(long='ra', type=string)
def ra(self, value):
'''
Help for RA
'''
# validate
# return valid value or throw ValueError
When you define a Parameter using @parameter decorator,
the name of the decorated function will be available in the options
dictionary passed to every action. Otherwise, you need to use name
keyword to define different names or to use with attribute based parameters
Before run the selected action, ChimeraCLI runs the method
__start__, passing all the parameters and the action that would
run. After the action be runned, __stop__ would be called.

serialized and will run only when the previous one

then returns the time of completion (with an arbitrary
zero point to give small numbers). The deviation from the
mean of unlocked methods termination times should be
nearly zero, as every methods runs at the same time. For
locked ones, the termination time will be a linear
function with the slope equals to the load (sleep in this
case), and as we use 10 threads for the locked case, the
deviation will be ~ 2.872. We use a simple equals_eps to
